In this video, we’ll learn how JavaScript engines use the JIT (Just-In-Time) compiler to make code run faster. ⚡

You’ll understand:

The difference between Compiler and Interpreter
How JIT Compilation combines both for better performance
The role of AST (Abstract Syntax Tree), Interpreter, and Compiler in the JavaScript engine
How browsers optimize repeated code for speed
By the end, you’ll know exactly how your JavaScript code turns into machine code inside engines.
