Functions for Reusability
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.
