Javascript: JavaScript is a programming language that adds interactivity to your website.

• talk about variables
• looping over
  • for - loops through a block of code a number of times
  • for/in - loops through the properties of an object (in case we want the keys -- do not use it if we care about the order)
  • for/of - loops through the values of an iterable object (to get the values - best with arrays)
• Others are forEach

Key points:

• A semicolon at the end of a line indicates where a statement ends.
• JavaScript is case sensitive.
