freeCodeCamp Challenge Guide: Write Reusable JavaScript with Functions

Write Reusable JavaScript with Functions


Problem Explanation

Functions allow you to reuse code over and over. Our task is to make a simple reusableFunction() that prints out “Hi World” to the console (which you can reach with Ctrl + Shift + I).

You start off by using the function keyword, and then typing the function name (which follows Camel Case formatting). Then, type the (), and create the {} brackets. Like so:

function reusableFunction() {}

Now, your function is ready to be typed in. Use the console.log() to print a message in the console.
