Hey all, this JavaScript tutorial for beginners will introduce the concept of variable scope. Variables can have either global or local scope.

A global variable is initialized at the ‘top-level’ of your document, and can be used anywhere within your document after it has been declared. A local variable has only local scope, and can only be used within the function in which it was initialized.

As always, fire away with any questions 🙂
