Resize an array with JavaScript is easy

ArrayResize.js

var array = [1, 2, 3, 4, 5];
console.log(array.length); // 5

array.length--;
console.log(array.length); // 4

array.length += 15;
console.log(array.length); // 19

Short and useful example. So basically length serves dual purpose.

this changes only the length and does not add null values.

thanks bro.

So which elements are kept?

Here's a running example @dzonekl, the elements at the end of the array are removed.
