Chapter 6 Lab

If you want to become a programmer, you will need to study one or more languages. You have a variety of options available, including online materials, in-person classes, and study guides. While this chapter certainly didn’t teach you everything you need to know to become a programmer, you did learn some concepts and a bit about how to read and understand code. For this lab, you will look at a few different websites and see how their code was constructed.

Open the website www.youtube.com in Chrome or Edge. To view the source code in Chrome, right-click the page, and choose View Page Source. In Edge, press the F12 key to show the code. (Or, you can click the Settings And More menu—the three horizontal dots in the upper-right corner—and click F12 Developer Tools.)
