Want to learn how to code but don't know where to start? We've got you covered. We'll be teaching you the basics all week, and here's your first lesson.
Previously we've provided you with some resources for learning to code and given you a broad overview of the process, but now it's time to get down to business: We're offering a short 101 course, step by step. You can't learn to code overnight (or in a week), but we've broken up the basics into a few

Let's get started!
What Are Variables?
You can think of variables as labeled jars that store different types of data. While there are several kinds of variables, today we're only going to look at three:
• String - A string variable is a string of alphanumeric characters and allowed symbols that are contained within quotation marks.
