Beginners, you may gloss over this reply if you like, we'll cover this stuff soon enough.

Do you have to declare your variable types such as a string, a whole number etc?

Not in Javascript... in Javascript, a basic variable can contain a boolean, a character, a number, or a string. In more advanced languages, this distinction is necessary, but not in JS.

In the example of madlibs code, what are the commands for input and output of strings such as the "get" command?

Javascript have a built-in function called prompt() which asks the user for a value, and returns it. That's how we'd retreive the words from the user. We can then print those back out to the browser with a document.write() command.

No... a double equal is the test operator... if (myNumber == 10). A single equal is the assignment operator... myNumber = 15; If you want to test for Not Equals, you use the != operator.

A post on Javascript operators will be coming up shortly.
