Array-extra-methods NPM

Node.js Array Extra methods

Those are some extra methods for the Array prototype in nodejs. I will add to it any methods that I find useful, but that are not implemented by default.

Installing

npm install array-extra-methods

Implemented methods

Array.prototype.sample = function()
- Returns a random element from the array
Array.prototype.take = function()
- Returns a random element from the array and removes the element from it
Array.prototype.last = function()
- Returns the last element from the array
Array.prototype.shuffle = function()
- Shuffles the values of the array
Array.prototype.shuffled = function()
- Returns a copy of the array with shuffled elements
Array.prototype.swap = function(ind1, ind2)
- Swaps both values of an array
Array.prototype.high = function()
- Returns the last index of the array
Array.prototype.group = function(amount)
- Divides the array into "amount" groups, don't change the array
Array.prototype.groupLen = function(amount)
