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)

    • Divides the array into groups of 'len' length, don't change the array
