Three Steps to Faster JavaScript Programming

There are three steps that you can follow that will help you learn how to write JavaScript faster, easier, and with a lot less frustration.

(1) Use the HTML Validator add-on for FireFox to make certain your HTML code is valid.

(2) Use the Console tab in FireBug to check for any JavaScript errors you may have in your code. This is a great way to check for misspelled variable and function names as well as missing quotes or concatenation operators "+".

(3) Finally, use the breakpoint and stepping tools in FireBug to step through your program.

This video is an in-class demonstration showing how to use the FireBug console to catch JavaScript errors as well as CSS errors. It is part of the Programming Fundamentals course (JavaScript) offered by Computer Careers at South Central College in North Mankato, Minnesota.
