To start, a variable in JavaScript is essentially the name of a storage location for data we collect. These variables can be used to store a wide variety of data such as products offered in the store, information regarding visitors and other data collected from interactions. Now if you are looking to create a variable in JavaScript, there are some specific directions you need to follow. The first step is to get Javascript booted up on your computer and then you get into your line of code and the first think you type is let and then what you want the variable to be. So in this example you can type message; after let to create the variable. You then would type what your message is by typing message = ‘Hello’; to make your message say hello. If you want your message to appear you then you must type another line of code where it says alert(message);. This will allow you to utilize your variable and alert the user when they land your page.

Hi Ryan! These are great examples you shared to get a better understanding of JavaScript variables. I think highlighting what we learned during the class and how the code will be interpreted by our computer is important. Learning the purpose of variables and what steps to follow to get a specific action is the first step to learning how to code. Through practice from our class assignments, it’s amazing to see your code come alive through the variables created!
