Demystifying scope and closures in JavaScript

- [Instructor] As a JavaScript developer, some of our trickiest bugs emerge when managing the scope of variables. With different rules for syntax and keywords, it can be challenging to make sure our functions return the correct results. In this course, I'll challenge you to write code to practice with the most common patterns in JavaScript functions.
