Having data is no use if you can’t do anything with it, so step forward operators. Operators do just what their name suggests; they operate on things. In the case of JavaScript, those things are the values stored in variables and any other value used in your script. For example, we’d use a division operator to divide one value by another value to return a result. There are some very straightforward operators in JavaScript and some not-so-straightforward ones; we’ll cover all the useful ones and mention the others in passing, even though you will never use them.
