JavaScript Variables!

Let's review how to declare them the right way🤔

There are a few general rules for naming variables:⁣⁣

⁣▪️Variable names cannot start with numbers.⁣⁣

⁣⁣▪️Variable names are case sensitive, so myName and myname would be different variables. It is bad practice to create two variables that have the same name using different cases.⁣⁣

⁣⁣▪️Variable names cannot be the same as keywords. For a comprehensive list of keywords check out MDN’s keyword documentation.⁣⁣
