Your First Function — JavaScript typing lesson

Create functions to reuse code blocks.

What you'll practice

Let's teach our program a new trick! A function is a block of code we can name and use over and over.

  • `function say_hello() {` starts the definition of our new function.
  • The code inside the function goes between the curly braces {}.
