mutable-array

Functions to modify an array in-place instead of making a copy.

example

var mmap = require('mutable-array').mmap;
var a = [1,2,3,4,5];
 
mmap(a, function (val) {
    return val + 1;
});
 
console.log(a);
 
//[2,3,4,5,6];

api

mmap([array,] callback, thisArg)

Standard Array.map functionality, but values that are returned from callback replace the original element in the array.

mfilter([array,] callback, thisArg)

Standard Array.filter functionality, but removes (using splice) values from the array if value returned from callback does not equal true.

applyPrototype()

Add all functions to the Array prototype.
