JavaScript Switch statement is used when we have a lot of variables that we want to match. In the following example we get the day of the week. We can then show something for each day of the week.

Getting A Day JavaScript Built In Function *

There are already functions that JavaScript comes with in every browser. The one we are going to use is they date. There are different variations of the date that you can get. We are going to focus on the day of the week. We use new Date().getDay to get the numbers 0 through 6. 0 is Sunday while 6 is Saturday.
