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!
# iterNonSquaresSeq
[![NPM version][npm-image]][npm-url] [![Build Status][test-image]][test-url] [![Coverage Status][coverage-image]][coverage-url]
> Create an iterator which generates a sequence of [nonsquares][oeis-a000037].
## Installation
```bash
npm install @stdlib/math-iter-sequences-nonsquares
```
Alternatively,
- To load the package in a website via a `script` tag without installation and bundlers, use the [ES Module][es-module] available on the [`esm`][esm-url] branch (see [README][esm-readme]).
- If you are using Deno, visit the [`deno`][deno-url] branch (see [README][deno-readme] for usage intructions).
- For use in Observable, or in browser/node environments, use the [Universal Module Definition (UMD)][umd] build available on the [`umd`][umd-url] branch (see [README][umd-readme]).
The [branches.md][branches-url] file summarizes the available branches and displays a diagram illustrating their relationships.
To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.
## Usage
```javascript
var iterNonSquaresSeq = require( '@stdlib/math-iter-sequences-nonsquares' );
```
#### iterNonSquaresSeq( \[options] )
Returns an iterator which generates a sequence of nonsquares.
```javascript
var it = iterNonSquaresSeq();
// returns
var v = it.next().value;
// returns 2
v = it.next().value;
// returns 3
v = it.next().value;
// returns 5
v = it.next().value;
// returns 6
v = it.next().value;
// returns 7
// ...
```
The returned iterator protocol-compliant object has the following properties:
- **next**: function which returns an iterator protocol-compliant object containing the next iterated value (if one exists) assigned to a `value` property and a `done` property having a `boolean` value indicating whether the iterator is finished.
- **return**: function which closes an iterator and returns a single (optional) argument in an iterator protocol-compliant object.
The function supports the following `options`:
- **iter**: number of iterations. Default: `9007199349647256`.
By default, the function returns a finite iterator to avoid exceeding the maximum safe double-precision floating-point integer. To adjust the number of iterations, set the `iter` option.
```javascript
var opts = {
'iter': 2
};
var it = iterNonSquaresSeq( opts );
// returns
var v = it.next().value;
// returns 2
v = it.next().value;
// returns 3
var bool = it.next().done;
// returns true
```
## Notes
- If an environment supports `Symbol.iterator`, the returned iterator is iterable.
## Examples
```javascript
var iterNonSquaresSeq = require( '@stdlib/math-iter-sequences-nonsquares' );
// Create an iterator:
var opts = {
'iter': 100
};
var it = iterNonSquaresSeq( opts );
// Perform manual iteration...
var v;
while ( true ) {
v = it.next();
if ( v.done ) {
break;
}
console.log( v.value );
}
```
