I have a <textarea> that allows text to be inputted in the form of a string. Then the users clicks on a button which displays what they have inputted back to them in a text area within a table.

I need to use an array to store what has been inputted by the user, and then display it back out into another <textarea> element within a table from the array, where the user input is stored from the input box.

Any pointers on how to fill up an array and stacks, from a user input would be great.

You can declare your array like this

var yourArray = new Array();

or

var yourArray = [];

To add items to array:

yourArray.push(yourString);

To get you can use indexing like (almost any other language)

yourArray[i]

You can even set as an object array like this:

yourArray.push({ text : 'blablabla'})

So, in your case, filling up the array could be something like this:

var inputText = document.getElementById('id_of_input').value;
yourArray.push(inputText);

// show it

for(var i=0; i<yourArray.length; i++) {
    alert(yourArray[i]);
}
