FUNCTION PARAMETERS BYTE CODE | How JavaScript REALLY works | V8 engine explained | Advanced JS
In this video we will look at how your Javascript code works at a bytecode level. In particular in this tutorial we deep dive into how Javascript V8 virtual machine (VM) represents function parameters as address registers. We also look at how functions are called in JavaScript at a bytecode level and how those address registers are accessed. We further deep dive into the accumulator and how data is moved between parameters and the accumulator to perform calculations using parameters. This also provides a pretty definitive view on how JavaScript defaults parameters.
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.
