What is the difference between methods and functions? When should you use them?

Methods and Functions are pretty much the same thing. They should be used when you have a task that you want to be able to repeat, but not have to rewrite the code over and over again. Instead you would just call the method/function to handle the task. For example, if you need to calculate a value multiple times using the same expression.

A method is just a function that is associated with an object. So if you have a function that belongs to an object, it would be called a method of that object.

So, function - a block of code that can be repeated by calling it.

Method - a function that belongs to an object and describes some behavior of that object.

Good luck!

The "FUNCTION" can be called directly when an event occurs (like when a user clicks a button), and it can be called from "anywhere" by JavaScript code.

A "METHOD" is just an object property that happens to be a function.
