    array-range

    creates a new array with given range. Study from mattdesl/array-range

    Tiny module to create a new dense array with the specified range.

    var range = require('array-range')
    range(3)       // -> [ 0, 1, 2 ]
    range(1, 4)    // -> [ 1, 2, 3 ]

    Mainly useful for functional programming. ES6 examples:

    var array = require('array-range')
     
    array(5).map( x => x*)
    // -> [ 0, 1, 4, 9, 16 ]
     
    array(2, 10).filter( x => x%2===0 )
    // -> [ 2, 4, 6, 8 ]

    It can also be useful for creating a fixed size dense array. Cleaner than apply and does not create an intermediate array:

    array(5)
     
    //vs.
     
    Array.apply(null, new Array(5))

    Usage

    array(start, end)

    Creates a new dense array with a length of end-start elements. start is inclusive, end is exclusive. Negative values also work, e.g. range(-10, 10)

    array(len)

    Creates a new dense array with len number of elements, from zero to len-1.

    If len is unspecified, it defaults to zero (empty array).
