Understanding Lexical environment and scope chaining with the help of browser

🔍 Understanding Lexical Environment & Scope Chaining in JavaScript (with Browser Demo)

In this short, I’ve clearly explained how Lexical Environment and Scope Chaining work in JavaScript using the browser’s Developer Tools. You’ll learn how JavaScript searches for variables—starting from the local scope, moving up to parent scopes, and finally the global scope.

Using visual examples in the browser, I break down:

What a Lexical Environment actually is

How Scope Chaining resolves variables

How JavaScript builds the scope chain during execution

Perfect for beginners and intermediate devs who want to master how variable resolution works behind the scenes. 🎯
