The type of error that occurs when a variable is referenced before it has been defined is called a "ReferenceError". This error typically occurs in JavaScript when you try to use a variable that doesn't exist or is not yet defined.

Here are the steps that lead to a ReferenceError:

1. You write code that refers to a variable.
2. You run this code before the variable has been defined.
3. JavaScript attempts to execute your code.
4. Because JavaScript doesn't know what the undefined variable is supposed to represent, it throws a "ReferenceError".

To avoid this error, you should always declare and initialize your variables before you use them in your code.
