# What are the scopes of a variable in JavaScript ?

That is 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 in Javascript** − The global variable has a global scope which means this is visible everywhere in your JavaScript code.

**Local Variables in Javascript** − The local variable will be visible only within a function where it is defined. The function parameters are always local to that function.
