About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.


The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.


When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.


To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

### Methods

#### Uint16Array.from( src\[, map\[, thisArg]] )

Creates a new typed array from an array-like `object` or an iterable.

```javascript
var arr = Uint16Array.from( [ 1, 2 ] );
// returns [ 1, 2 ]
```

To invoke a function for each `src` value, provide a callback function.

```javascript
function mapFcn( v ) {
return v * 2;
}

var arr = Uint16Array.from( [ 1, 2 ], mapFcn );
// returns [ 2, 4 ]
```

A callback function is provided two arguments:

- `value`: source value
- `index`: source index

To set the callback execution context, provide a `thisArg`.

```javascript
function mapFcn( v ) {
this.count += 1;
return v * 2;
}

var ctx = {
'count': 0
};

var arr = Uint16Array.from( [ 1, 2 ], mapFcn, ctx );
// returns [ 2, 4 ]

var n = ctx.count;
// returns 2
```

#### Uint16Array.of( element0\[, element1\[, ...elementN]] )

Creates a new typed array from a variable number of arguments.

```javascript
var arr = Uint16Array.of( 1, 2 );
// returns [ 1, 2 ]
```

#### Uint16Array.prototype.copyWithin( target, start\[, end] )

Copies a sequence of elements within an array starting at `start` and ending at `end` (non-inclusive) to the position starting at `target`.

```javascript
var arr = new Uint16Array( [ 1, 2, 3, 4, 5 ] );

// Copy the last two elements to the first two elements:
arr.copyWithin( 0, 3 );

var v = arr[ 0 ];
// returns 4

v = arr[ 1 ];
// returns 5
```

By default, `end` equals the number of array elements (i.e., one more than the last array index). To limit the sequence length, provide an `end` argument.

```javascript
var arr = new Uint16Array( [ 1, 2, 3, 4, 5 ] );

// Copy the first two elements to the last two elements:
arr.copyWithin( 3, 0, 2 );

var v = arr[ 3 ];
// returns 1

v = arr[ 4 ];
// returns 2
```

When a `target`, `start`, and/or `end` index is negative, the respective index is determined relative to the last array element. The following example achieves the same behavior as the previous example:

```javascript
var arr = new Uint16Array( [ 1, 2, 3, 4, 5 ] );

// Copy the first two elements to the last two elements:
arr.copyWithin( -2, -5, -3 );

var v = arr[ 3 ];
// returns 1

v = arr[ 4 ];
// returns 2
```

#### Uint16Array.prototype.entries()

Returns an iterator for iterating over array key-value pairs.

```javascript
var arr = new Uint16Array( [ 1, 2 ] );

// Create an iterator:
var it = arr.entries();

// Iterate over key-value pairs...
var v = it.next().value;
// returns [ 0, 1 ]

v = it.next().value;
// returns [ 1, 2 ]

var bool = it.next().done;
// returns true
```

#### Uint16Array.prototype.every( predicate\[, thisArg] )

Tests whether all array elements pass a test implemented by a `predicate` function.

```javascript
function predicate( v ) {
return ( v <= 1 );
}

var arr = new Uint16Array( [ 1, 2 ] );

var bool = arr.every( predicate );
// returns false
```

A `predicate` function is provided three arguments:

- `value`: array element
- `index`: array index
- `arr`: array on which the method is invoked

To set the callback execution context, provide a `thisArg`.

```javascript
function predicate( v ) {
this.count += 1;
return ( v >= 1 );
}

var ctx = {
'count': 0
};

var arr = new Uint16Array( [ 1, 2 ] );

var bool = arr.every( predicate, ctx );
// returns true

var n = ctx.count;
// returns 2
```

#### Uint16Array.prototype.fill( value\[, start\[, end]] )

Fills an array from a `start` index to an `end` index (non-inclusive) with a provided `value`.

```javascript
var arr = new Uint16Array( 2 );

// Set all array elements to the same value:
arr.fill( 2 );

var v = arr[ 0 ];
// returns 2

v = arr[ 1 ];
// returns 2

// Set all array elements starting from the first index to the same value:
arr.fill( 3, 1 );

v = arr[ 0 ];
// returns 2

v = arr[ 1 ];
// returns 3

// Set all array elements, except the last element, to the same value:
arr.fill( 4, 0, arr.length-1 );

v = arr[ 0 ];
// returns 4

v = arr[ 1 ];
// returns 3
```

When a `start` and/or `end` index is negative, the respective index is determined relative to the last array element.

```javascript
var arr = new Uint16Array( 2 );

// Set all array elements, except the last element, to the same value:
arr.fill( 2, -arr.length, -1 );

var v = arr[ 0 ];
// returns 2

v = arr[ 1 ];
// returns 0
```

#### Uint16Array.prototype.filter( predicate\[, thisArg] )

Creates a new array (of the same data type as the host array) which includes those elements for which a `predicate` function returns a truthy value.

```javascript
function predicate( v ) {
return ( v >= 2 );
}

var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.filter( predicate );
// returns [ 2, 3 ]
```

If a `predicate` function does not return a truthy value for any array element, the method returns an empty array.

```javascript
function predicate( v ) {
return ( v >= 10 );
}

var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.filter( predicate );
// returns []
```

A `predicate` function is provided three arguments:

- `value`: array element
- `index`: array index
- `arr`: array on which the method is invoked

To set the callback execution context, provide a `thisArg`.

```javascript
function predicate( v ) {
this.count += 1;
return ( v >= 2 );
}

var ctx = {
'count': 0
};

var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.filter( predicate, ctx );

var n = ctx.count;
// returns 3
```

#### Uint16Array.prototype.find( predicate\[, thisArg] )

Returns the first array element for which a provided `predicate` function returns a truthy value.

```javascript
function predicate( v ) {
return ( v > 2 );
}

var arr = new Uint16Array( [ 1, 2, 3 ] );

var v = arr.find( predicate );
// returns 3
```

If a `predicate` function does not return a truthy value for any array element, the method returns `undefined`.

```javascript
function predicate( v ) {
return ( v < 1 );
}

var arr = new Uint16Array( [ 1, 2, 3 ] );

var v = arr.find( predicate );
// returns undefined
```

A `predicate` function is provided three arguments:

- `value`: array element
- `index`: array index
- `arr`: array on which the method is invoked

To set the callback execution context, provide a `thisArg`.

```javascript
function predicate( v ) {
this.count += 1;
return ( v > 2 );
}

var ctx = {
'count': 0
};

var arr = new Uint16Array( [ 1, 2, 3 ] );

var v = arr.find( predicate, ctx );
// returns 3

var n = ctx.count;
// returns 3
```

#### Uint16Array.prototype.findIndex( predicate\[, thisArg] )

Returns the index of the first array element for which a provided `predicate` function returns a truthy value.

```javascript
function predicate( v ) {
return ( v >= 3 );
}

var arr = new Uint16Array( [ 1, 2, 3 ] );

var idx = arr.findIndex( predicate );
// returns 2
```

If a `predicate` function does not return a truthy value for any array element, the method returns `-1`.

```javascript
function predicate( v ) {
return ( v < 1 );
}

var arr = new Uint16Array( [ 1, 2, 3 ] );

var idx = arr.findIndex( predicate );
// returns -1
```

A `predicate` function is provided three arguments:

- `value`: array element
- `index`: array index
- `arr`: array on which the method is invoked

To set the callback execution context, provide a `thisArg`.

```javascript
function predicate( v ) {
this.count += 1;
return ( v >= 3 );
}

var ctx = {
'count': 0
};

var arr = new Uint16Array( [ 1, 2, 3 ] );

var idx = arr.findIndex( predicate, ctx );
// returns 2

var n = ctx.count;
// returns 3
```

#### Uint16Array.prototype.forEach( fcn\[, thisArg] )

Invokes a callback for each array element.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var str = '';

function fcn( v, i ) {
str += i + ':' + v;
if ( i < arr.length-1 ) {
str += ' ';
}
}

arr.forEach( fcn );

console.log( str );
// => '0:1 1:2 2:3'
```

The callback is provided three arguments:

- `value`: array element
- `index`: array index
- `arr`: array on which the method is invoked

To set the callback execution context, provide a `thisArg`.

```javascript
function fcn() {
this.count += 1;
}

var ctx = {
'count': 0
};

var arr = new Uint16Array( [ 1, 2, 3 ] );

arr.forEach( fcn, ctx );

var n = ctx.count;
// returns 3
```

#### Uint16Array.prototype.includes( searchElement\[, fromIndex] )

Returns a `boolean` indicating whether an array includes a search element.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var bool = arr.includes( 3 );
// returns true

bool = arr.includes( 0 );
// returns false
```

By default, the method searches the entire array (`fromIndex = 0`). To begin searching from a specific array index, provide a `fromIndex`.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var bool = arr.includes( 1, 1 );
// returns false
```

When a `fromIndex` is negative, the starting index is resolved relative to the last array element.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var bool = arr.includes( 1, -2 );
// returns false
```

#### Uint16Array.prototype.indexOf( searchElement\[, fromIndex] )

Returns the index of the first array element strictly equal to a search element.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var idx = arr.indexOf( 3 );
// returns 2

idx = arr.indexOf( 0 );
// returns -1
```

By default, the method searches the entire array (`fromIndex = 0`). To begin searching from a specific array index, provide a `fromIndex`.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var idx = arr.indexOf( 1, 1 );
// returns -1
```

When a `fromIndex` is negative, the starting index is resolved relative to the last array element.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var idx = arr.indexOf( 1, -2 );
// returns -1
```

#### Uint16Array.prototype.join( \[separator] )

Serializes an array by joining all array elements as a string.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var str = arr.join();
// returns '1,2,3'
```

By default, the method delineates array elements using a comma `,`. To specify a custom separator, provide a `separator` string.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var str = arr.join( '|' );
// returns '1|2|3'
```

#### Uint16Array.prototype.keys()

Returns an iterator for iterating over array keys.

```javascript
var arr = new Uint16Array( [ 1, 2 ] );

// Create an iterator:
var it = arr.keys();

// Iterate over keys...
var v = it.next().value;
// returns 0

v = it.next().value;
// returns 1

var bool = it.next().done;
// returns true
```

#### Uint16Array.prototype.lastIndexOf( searchElement\[, fromIndex] )

Returns the index of the last array element strictly equal to a search element, iterating from right to left.

```javascript
var arr = new Uint16Array( [ 1, 0, 2, 0, 1 ] );

var idx = arr.lastIndexOf( 0 );
// returns 3

idx = arr.lastIndexOf( 3 );
// returns -1
```

By default, the method searches the entire array (`fromIndex = -1`). To begin searching from a specific array index, provide a `fromIndex`.

```javascript
var arr = new Uint16Array( [ 1, 0, 2, 0, 1 ] );

var idx = arr.lastIndexOf( 0, 2 );
// returns 1
```

When a `fromIndex` is negative, the starting index is resolved relative to the last array element.

```javascript
var arr = new Uint16Array( [ 1, 0, 2, 0, 1 ] );

var idx = arr.lastIndexOf( 0, -3 );
// returns 1
```

#### Uint16Array.prototype.map( fcn\[, thisArg] )

Maps each array element to an element in a new array having the same data type as the host array.

```javascript
function fcn( v ) {
return v * 2;
}

var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.map( fcn );
// returns [ 2, 4, 6 ]
```

A callback is provided three arguments:

- `value`: array element
- `index`: array index
- `arr`: array on which the method is invoked

To set the callback execution context, provide a `thisArg`.

```javascript
function fcn( v ) {
this.count += 1;
return v * 2;
}

var ctx = {
'count': 0
};

var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.map( fcn, ctx );

var n = ctx.count;
// returns 3
```

#### Uint16Array.prototype.reduce( fcn\[, initialValue] )

Applies a function against an accumulator and each element in an array and returns the accumulated result.

```javascript
function fcn( acc, v ) {
return acc + ( v*v );
}

var arr = new Uint16Array( [ 2, 1, 3 ] );

var v = arr.reduce( fcn );
// returns 12
```

If not provided an initial value, the method invokes a provided function with the first array element as the first argument and the second array element as the second argument.

If provided an initial value, the method invokes a provided function with the initial value as the first argument and the first array element as the second argument.

```javascript
function fcn( acc, v ) {
return acc + ( v*v );
}

var arr = new Uint16Array( [ 2, 1, 3 ] );

var v = arr.reduce( fcn, 0 );
// returns 14
```

A callback is provided four arguments:

- `acc`: accumulated result
- `value`: array element
- `index`: array index
- `arr`: array on which the method is invoked

#### Uint16Array.prototype.reduceRight( fcn\[, initialValue] )

Applies a function against an accumulator and each element in an array and returns the accumulated result, iterating from right to left.

```javascript
function fcn( acc, v ) {
return acc + ( v*v );
}

var arr = new Uint16Array( [ 2, 1, 3 ] );

var v = arr.reduceRight( fcn );
// returns 8
```

If not provided an initial value, the method invokes a provided function with the last array element as the first argument and the second-to-last array element as the second argument.

If provided an initial value, the method invokes a provided function with the initial value as the first argument and the last array element as the second argument.

```javascript
function fcn( acc, v ) {
return acc + ( v*v );
}

var arr = new Uint16Array( [ 2, 1, 3 ] );

var v = arr.reduce( fcn, 0 );
// returns 14
```

A callback is provided four arguments:

- `acc`: accumulated result
- `value`: array element
- `index`: array index
- `arr`: array on which the method is invoked

#### Uint16Array.prototype.reverse()

Reverses an array **in-place** (thus mutating the array on which the method is invoked).

```javascript
var arr = new Uint16Array( [ 2, 0, 3 ] );

// Reverse the array:
arr.reverse();

var v = arr[ 0 ];
// returns 3

v = arr[ 1 ];
// returns 0

v = arr[ 2 ];
// returns 2
```

#### Uint16Array.prototype.set( arr\[, offset] )

Sets array elements.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );
// returns [ 1, 2, 3 ]

// Set the first two array elements:
arr.set( [ 4, 5 ] );

var v = arr[ 0 ];
// returns 4

v = arr[ 1 ];
// returns 5
```

By default, the method starts writing values at the first array index. To specify an alternative index, provide an index `offset`.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );
// returns [ 1, 2, 3 ]

// Set the last two array elements:
arr.set( [ 4, 5 ], 1 );

var v = arr[ 1 ];
// returns 4

v = arr[ 2 ];
// returns 5
```

#### Uint16Array.prototype.slice( \[begin\[, end]] )

Copies array elements to a new array with the same underlying data type as the host array.

```javascript
var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.slice();

var bool = ( arr1 === arr2 );
// returns false

bool = ( arr1.buffer === arr2.buffer );
// returns false

var v = arr2[ 0 ];
// returns 1

v = arr2[ 1 ];
// returns 2

v = arr2[ 2 ];
// returns 3
```

By default, the method copies elements beginning with the first array element. To specify an alternative array index at which to begin copying, provide a `begin` index (inclusive).

```javascript
var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.slice( 1 );

var len = arr2.length;
// returns 2

var v = arr2[ 0 ];
// returns 2

v = arr2[ 1 ];
// returns 3
```

By default, the method copies all array elements after `begin`. To specify an alternative array index at which to end copying, provide an `end` index (exclusive).

```javascript
var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.slice( 0, 2 );

var len = arr2.length;
// returns 2

var v = arr2[ 0 ];
// returns 1

v = arr2[ 1 ];
// returns 2
```

When a `begin` and/or `end` index is negative, the respective index is determined relative to the last array element.

```javascript
var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.slice( -arr1.length, -1 );

var len = arr2.length;
// returns 2

var v = arr2[ 0 ];
// returns 1

v = arr2[ 1 ];
// returns 2
```

#### Uint16Array.prototype.some( predicate\[, thisArg] )

Tests whether at least one array element passes a test implemented by a `predicate` function.

```javascript
function predicate( v ) {
return ( v >= 2 );
}

var arr = new Uint16Array( [ 1, 2 ] );

var bool = arr.some( predicate );
// returns true
```

A `predicate` function is provided three arguments:

- `value`: array element
- `index`: array index
- `arr`: array on which the method is invoked

To set the callback execution context, provide a `thisArg`.

```javascript
function predicate( v ) {
this.count += 1;
return ( v >= 2 );
}

var ctx = {
'count': 0
};

var arr = new Uint16Array( [ 1, 1 ] );

var bool = arr.some( predicate, ctx );
// returns false

var n = ctx.count;
// returns 2
```

#### Uint16Array.prototype.sort( \[compareFunction] )

Sorts an array **in-place** (thus mutating the array on which the method is invoked).

```javascript
var arr = new Uint16Array( [ 2, 3, 0 ] );

// Sort the array (in ascending order):
arr.sort();

var v = arr[ 0 ];
// returns 0

v = arr[ 1 ];
// returns 2

v = arr[ 2 ];
// returns 3
```

By default, the method sorts array elements in ascending order. To impose a custom order, provide a `compareFunction`.

```javascript
function descending( a, b ) {
return b - a;
}

var arr = new Uint16Array( [ 2, 3, 0 ] );

// Sort the array (in descending order):
arr.sort( descending );

var v = arr[ 0 ];
// returns 3

v = arr[ 1 ];
// returns 2

v = arr[ 2 ];
// returns 0
```

The comparison function is provided two array elements, `a` and `b`, per invocation, and its return value determines the sort order as follows:

- If the comparison function returns a value **less** than zero, then the method sorts `a` to an index lower than `b` (i.e., `a` should come **before** `b`).
- If the comparison function returns a value **greater** than zero, then the method sorts `a` to an index higher than `b` (i.e., `b` should come **before** `a`).
- If the comparison function returns **zero**, then the relative order of `a` and `b` _should_ remain unchanged.

#### Uint16Array.prototype.subarray( \[begin\[, end]] )

Creates a new typed array view over the same underlying [`ArrayBuffer`][@stdlib/array/buffer] and with the same underlying data type as the host array.

```javascript
var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.subarray();
// returns [ 1, 2, 3 ]

var bool = ( arr1.buffer === arr2.buffer );
// returns true
```

By default, the method creates a typed array view beginning with the first array element. To specify an alternative array index at which to begin, provide a `begin` index (inclusive).

```javascript
var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.subarray( 1 );
// returns [ 2, 3 ]

var bool = ( arr1.buffer === arr2.buffer );
// returns true
```

By default, the method creates a typed array view which includes all array elements after `begin`. To limit the number of array elements after `begin`, provide an `end` index (exclusive).

```javascript
var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.subarray( 0, 2 );
// returns [ 1, 2 ]

var bool = ( arr1.buffer === arr2.buffer );
// returns true
```

When a `begin` and/or `end` index is negative, the respective index is determined relative to the last array element.

```javascript
var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.subarray( -arr1.length, -1 );
// returns [ 1, 2 ]

var bool = ( arr1.buffer === arr2.buffer );
// returns true
```

If the method is unable to resolve indices to a non-empty array subsequence, the method returns an empty typed array.

```javascript
var arr1 = new Uint16Array( [ 1, 2, 3 ] );

var arr2 = arr1.subarray( 10, -1 );
// returns []
```

#### Uint16Array.prototype.toLocaleString( \[locales\[, options]] )

Serializes an array as a locale-specific `string`.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var str = arr.toLocaleString();
// returns '1,2,3'
```

#### Uint16Array.prototype.toString()

Serializes an array as a `string`.

```javascript
var arr = new Uint16Array( [ 1, 2, 3 ] );

var str = arr.toString();
// returns '1,2,3'
```

#### Uint16Array.prototype.values()

Returns an iterator for iterating over array elements.

```javascript
var arr = new Uint16Array( [ 1, 2 ] );

// Create an iterator:
var it = arr.values();

// Iterate over array elements...
var v = it.next().value;
// returns 1

v = it.next().value;
// returns 2

var bool = it.next().done;
// returns true
```

## Examples

```javascript
var randu = require( '@stdlib/random-base-randu' );
var round = require( '@stdlib/math-base-special-round' );
var ctor = require( '@stdlib/array-uint16' );

var arr;
var i;

arr = new ctor( 10 );
for ( i = 0; i < arr.length; i++ ) {
arr[ i ] = round( randu()*100.0 );
}
console.log( arr );
```
