JS interpreter written in TS using Babel to parse AST.
+ test harness to run public EcmaScript conformance test suite
Just for fun :)
Actually as the name implies it has something related to async construct.
This was my initial motivation - I wanted to write a POC of JS engine where you do no need to mark your code with async/await keywords and make it the default behavior
(the same way as in Rust you do not need to mark you variable to be const, instead you mark it with mut when needed).
This no-async part is not finished (I switched to something more important).
[Your code] -> Babel -> [AST] -> Interpreter
Actually Interpreter works with AST node-by-node executing constructs on-fly and creating appropriate in-memory structures that represent ES runtime concepts.
The interpreter as expected for a toy does support only a small subset of EcmaScript, but anyway conformance tests are executed against the codebase and some of tests and sub-suites pass (check here)!
