One of the big advantages to using Sass is being able to reuse code. The simplest form of this is using variables. Variables in Sass work just like they do in other scripting languages. You simply assign a value to a variable name and then you can use that variable name anywhere you like. This is super helpful for doing things like defining the hex value for the color "blue" and then you can use the name "blue" wherever you want to use that hex value. This makes it easy to update that value in one place instead of having to find every instance of it and update all of them.
