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. ❤️ Support for this channel comes from our friends at Scrimba – the coding platform that's reinvented interactive learning: https://scrimba.com/freecodecamp
