TEMPORARY VARIABLES AS REGISTERS | How the JavaScript REALLY engine works | JS V8 Engine Byte Code
This video continues on from our video on how registers work in the JavaScript V8 engine at a bytecode level. • REGISTERS | How the JavaScript REALLY...
This time we look at how the JS engine handles temporary assignments as registers.
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. But it's not just variables or constants but even temporary assignments are assigned a virtual register.
This tutorial shows you how your JavaScript code gets translated into assembly byte code for these temporary assignments, increasing your knowledge of how javascript works under the hood.
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.
