stupid question for people like you

- how do you exactly know how javascript works inside out?

- i am assuming it is not the most feasible of tasks to sit through the v8 source code with half a million files inside and figure out what part does what

- what level of c/c++ is actually needed to pull something off like this and if you are a beginner who can write some basic data structures and sorting functions,

- what is the roadmap to go from here to the point where you are writing your own browser engine or game engine or drivers for some hardware devices?
