What question? You don’t understand the information in the course?

Variables which are declared within a function, as well as the function parameters have local scope. That means, they are only visible within that function.

This means if, in your program, you declare const number = 1, the variable number will be accessible from anywhere in your code.

If you do something like declare function numbercounter(), and you declare const number = 1 inside the function, only this function will ever be able to interact with that variable.
