What is JavaScript AST, how to play with it?

Question

Abstract Syntax Tree.. I always heard that compile to SpiderMonkey AST on Github.
So, is that a actual standard of JS syntax tree? And there\'s V8, is V8 using the same

Answer 1

I know only of one specification of Javascript AST: https://github.com/estree/estree

It originated from publication of Dave Herman from Mozilla and since then evolved as community standard. So it should match SpiderMonkey at some degree but I'm not sure about V8 and JSC.

Would appreciate if someone could provide more information on the matter.
