REGISTERS | How the JavaScript REALLY engine works | JS V8 engine explained | Advanced JavaScript

Video Description

This video looks at how registers work in the JavaScript V8 engine at a bytecode level. Everytime you create a variable whether it's a let, const or a var, this will be ultimately represented as a virtual register in the V8 engine's register machine. This tutorial shows you how your JavaScript code gets translated into assembly byte code, how the variables gets represented as registers and how it works in conjuction with the accumulator to perform math operations. In this video you will get even more familiar with how the JavaScript v8 engine handles your code and how it's represented as assembly instructions, and you will learn a load more new assembly instructions at a byte code level. This video really focuses on how you can become an Advanced JavaScript developer through focusing on how your source code gets translated into bytecode by the ignition interpreter in the Javascript V8 engine that powers chrome, chromium browsers and nodejs. This video is beginner friendly.
