Why is there no semicolon after the value 37.5. I thought all variables have to end with a semicolon?

The first variable set in this Challenge, doesn't have a semicolon before I even start the challenge. Am I suppose to add it or is it a mistake?

var temperature = 37.5

You are right. It's mistake but... JS-engine "under the hood" automatically push semicolons and there is a great problem to not put it by yourself. Classical example: "What will function return?"

function test() {

It will return "undefined". Because JS-engine of your browser will put ";" after "return" statement automatically.
