Do you have the results of test262_runner.rb? I came to know about test262 at a talk by the porffor's author and something like https://github.com/CanadaHonk/porffor?tab=readme-ov-file#tes... in README would be great to show this progress. Great project by the way!

Yeah, at the moment it's passing about 12% of tests, but there is a lot of low hanging fruits to implement, especially considering I started the project two weeks ago. This doesn't mean I will hit 100% in linear time, unfortunately, cause there is a long tail of builtin types and functions, but as I started by implementing the "hard parts" I left some easy parts not done. For example I implemented only enough syntax to allow running conditionals and a while loop cause it was needed for the test262 harness, but I left all the other loops (for, for in, for of, do while) and conditional expressions (switch) unimplemented. Implementing them will be more or less analogous to existing implementations for if/else and while.

Once I finish implementing `await` and generators, which are the last hard to implement semantic concepts, I will be implementing those low hanging fruits. It's hard to say how much coverage that will give me, but just to give an example: currently 1200 tests fails, cause `object["foo"]` syntax is not implemented. Ie. `object.foo` works, but `object["foo"]` does not. It doesn't mean that those 1200 tests automatically will pass, cause they might be testing other stuff, but there is a lot of such relatively simple syntax ommissions that make hundreds of tests fail.

And yes, I would love to have a nice graph like porffor has! :D

Yes now I'm looking at the tests I can see that the coverage won't increase linearly, but 12% (with some of the hard parts) in two weeks is impressive. I starred the repo, good luck with your journey :)
