Functions With Ingredients (Parameters) — JavaScript typing lesson

Learn function parameters to make flexible functions.

What you'll practice

Let's make our functions more powerful by giving them ingredients, called parameters!

The parameter `name` is a variable that exists only inside the function.
When you call the function, you give it the value for the parameter, like `greet('Alice')`.
