If you really want to improve yourself as a Javascript engine then learn how the V8 engine takes the source code that you write and converts into code that runs in your browser or node.js to a byte code level

In this video we look at how the Javascript engine (v8) interprets your JS source code into byte code that runs on a virtual machine.

This is the first part of a series where we explore concepts such as interpretation (using ignition), assembly language (yes you will be able to understand assembly), accumulators, registers etc.

Even though this video goes into advanced javascript concepts, it's super beginner friendly and will helps you really understand how the Javascript v8 engine interprets your source code which will ultimately help you become a better Javascript developer as you will have learned the internals.
