Nodejs Array Remove Object remove(x)

Method Source Code

// Problem 2. Remove elements

// Write a function that removes all elements with a given value.
// Attach it to the array type.
// Read about prototype and how to attach methods.

// var arr = [1,2,1,4,1,3,4,1,111,3,2,1,'1'];
// arr.remove(1); //arr = [2,4,3,4,111,3,2,'1'];
