How to read the v8 source code?

JavaScript runs on many platforms and in different environments. We often forget about the low level infrastructure that makes it work. During this talk we are going to explore how to read the source code of v8. We'll see how to dig into different features of the language and understand how they work. This can give us a very deep understanding and make us a better JavaScript developers.

22. Aug 2, 2018 First look in ./src
23. Aug 2, 2018 Parsing code is in ./src/parsing
24. Aug 2, 2018
25. Aug 2, 2018 AST Nodes are defined in src/ast/ast.h
26. Aug 2, 2018 BytecodeGenerator walks the AST and generate bytecode for each node
