Instead of giving those instructions for every hamburger, we can group and name them as a single function:

function makeHamburger() {
  Add bread
  Add burger patty
  Add pickles
}

A function is a named sequence of instructions, packaged as a unit, that performs a specific task.

We’ve defined the function by giving it instructions and a name, but how do we use it? We use a function by calling it. When we call makeHamburger() we expect all of its steps to be executed.

Instructions

Build hamburgers with a function: In this example you can call the function by clicking the makeHamburger() button. Make three hamburgers by calling the function three times.
