Variables are used frequently in Javascript and many other coding languages.
In this video, we're going to talk about variables in code.
Variables, just like in Algebra, are when you have a letter or a word and it represents something else.
Here we're doing var x = \Briana\. When we reference \x\ later on, it's going to know that's Briana.
When we console.log(x), it's going to output \Briana\.
But be careful - if we put console.log(\x\), with the x in quotation marks, it will output the letter \x\.
What I want you to take away from this video is that variables exist in code, and you can store everything from a simple string all the way up to a function, all within a simple name.
