How for/while/do loops REALLY work in JavaScript and how they're all the same at a byte code level

In this video we will look at how your Javascript code works at a bytecode level.

We look in particular at how for loops, while loops are represented at a byte code level and how they are represented as the same underneath. Not only we do look at loops but we also look at conditionals such as if statements and ternary operators and how they are represented.

All in all, we use the popular FizzBuzz coding exercise to bring this to life, and we finish it off with a light bit of code golf.

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.
