# Mapify.js [![Build Status](https://travis-ci.org/toddmotto/mapify.svg)](https://travis-ci.org/toddmotto/mapify)

Mapify is a 0.7KB standalone module for map iteration over Arrays and Objects, in the same fashion `Array.prototype.map` works, but also includes `Object` iteration support and is faster than `.map` itself.

### Array mapping

Creates a new `Array` with the results of calling a provided function on every element in this `Array`.

##### Syntax

```javascript

mapify(arr, callback[, thisArg]);

// Callback parameters

// currentValue: The current element being processed in the array.

// index: The index of the current element being processed in the array.

// array: The array being mapped.

// thisArg (optional)

// Value to use as this when executing callback.

```

##### Example

```javascript

var mapped = mapify([1, 3, 9], function (currentValue, index, array) {

  return currentValue * currentValue;

})

console.log(mapped); // 1, 9, 81

```

### Object mapping

Creates a new `Object` with the results of calling a provided function on every property in this `Object`.

##### Syntax

```javascript

mapify(obj, callback[, thisArg]);

// Callback parameters

// currentValue: The current element being processed in the object.

// propName: The name of the current property being processed in the object.

// object: The object being mapped.

//

// thisArg (optional)

// Value to use as this when executing callback.

```

##### Example

```javascript

var mapped = mapify({ a: 1, b: 2, c: 3 }, function (currentValue, propName, object) {

  return currentValue * currentValue;

})

console.log(mapped); // { a: 1, b: 4, c: 9 }

```

## Installing with Bower

To install Mapify into your project using Bower, use the GitHub repository hook:

```

bower install https://github.com/toddmotto/mapify.git

```

## Manual installation

Drop your files into your required folders, make sure you're using the files from the `dist` folder, which is the compiled production-ready code. Ensure you place the script before the closing `

	

	

  

  var mapped = mapify([1, 3, 9], function (currentValue, index, array) {

    return currentValue * currentValue;

  })

  console.log(mapped);
