"Any code in the function after the return statement isn't run."

"Any code in the function after the return statement isn't run." What is the purpose on disabling the execution if you purposely added it? Example is below.

function getRandomNumber() { var randomNumber = Math.floor( Math.random() * 6 ) + 1; return randomNumber; alert("Hi"); }

You will have to alert before the return or after the function call. Most likely after the call. The purpose of a function is reusable code. If there is a return statement then the purpose of that reusable code is to get a value. A return statement "breaks" the function, basically signaling "okay we're done here, got what we needed" and passes whatever needs to be passed wherever it needs to go.
