Quite simply an array is variable that holds multiple variables. Say we had three user names David, John and Jenny. If we were to store these in normal variables we would have to use three lines of code because basic variables can only contain one value.

With the use of Arrays we can take the above code and put it into one line.

You can also create an array by using the array class shown below;

The beauty of arrays is that they allow you to add or remove from them at runtime. Lets look at some methods below;

pop() The pop method removes an item from the end of an array.

push() The push method does the opposite and adds to the array.

first we'll look at the push() method;

The toString method Returns a string that represents the elements in the specified array.

When we test the movie the output window will read "David, John"

pop() method Example

The output window reads "John" because the pop method Removes the last element from the array.

There are many more array methods that we'll no doubt come across in the next few chapters of this guide but for now it's best just to grasp the basics.
