JavaScript Tutorial For Beginners #7 – JavaScript Variables

Hey ninjas. In today’s JavaScript tutorial, we’ll be taking a look at what variables are from a birds eye view. Variables are at the heart of most programming languages, and JavaScript is no different in that respect.

Variables area a way of storing information (such as the pixel position of an element on a page, or the customer name, or email) and can be of any of the main JavaScript types (integers, strings, boolean values etc – we’ll cover these later).

We need to use variables in our JS programs, so that we can refer to different pieces of varying information for different parts of our scripts to run! For example, an image slider needs to store how many images are in the slider.

As always, fire away with any questions :).
