array.and

Implement and method for javascript arrays to merge arrays.

Installation

npm install array.and

Usage

In node.js simply require this module. Unlike most node modules, array.stride doesn't export anything. Instead it modifies the Array prototype to implement a new method: .and().

require('array.and');

In the browser simply include it. There are no node.js specific code used in the module. Either copy/paste the code into your own source or inclde it in a script tag:

<script src="array.and.js"></script>

Syntax

arr.and(array[,array, ...])

Parameters

  • array : Array to merge with this array. Multiple arrays can be passed to be merged.

Description

Array.prototype.and() merges the current array with other arrays returning the merged array. All the arrays are iterated together and the elements are inserted into the returned array in the order they are defined: this array, then the first argument, then the second argument (if any) etc.

If some array is shorter than others then its element will be inserted into the returned array as undefined when it runs out of elements.

Examples

Example: Merging two arrays

The following example merges two arrays:

var x = [1,2,3].and([4,5,6]);

// x is now:
[1,4,2,5,3,6]

Example: Merging three arrays

The following example merges three arrays of different sizes:

var x = [1,2,3].and([4,5],[6]);

// x is now:
[1,4,6,2,5,undefined,3,undefined,undefined]
