About This Class

2576be8d

Scope and Context are two very important concepts in JavaScript, and they are not the same thing.   Understanding the difference between Scope and Context will help you to write cleaner, more maintainable code and save you time when troubleshooting problems.

In this course, I will take you on a deep-dive into the world of Scope and Context. We will learn not only the difference between these two concepts, but also how to make the right decisions when planning your code and take the right steps when troubleshooting problems.

Guitarist

I have been playing guitar since 1978. Live performance has always been my specialty. I grew up on 70's Classic Rock and enjoy playing Blues, R&B, Soul and Funk as well. As a big fan of guitar building / modifications and general tinkering. I've had the pleasure of performing internationally with Blues Rock Band "The HEALERS!", Gospel Sensation Liz McComb and Nigerian Blues knockout Justina Lee Brown.
