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.
