The scope of a variable is the region of your program in which it is defined. JavaScript variable will have only two scopes.

Global Variables − A global variable has global scope which means it is visible everywhere in your JavaScript code.

Local Variables − A local variable will be visible only within a function where it is defined. Function parameters are always local to that function.
