10. Variable Scope JavaScript

In this course, you’ll explore the concept of variable scope in JavaScript, which determines where variables are accessible within your code. You’ll learn about the differences between global and local scope, and how to effectively manage your variables to prevent conflicts and unexpected behaviors. We’ll cover the implications of using var, let, and const for variable declarations, and how their scopes differ. By understanding variable scope, you’ll be able to write cleaner, more efficient code that avoids common pitfalls related to variable accessibility and lifetime.
