Amazing series! Would also love to see another series about building a compiler and type checking.

I agree. It would be nice to see other series that build on this one.

I'm following along implementing this in Rust. I have used enums to model the AST node types, and I already had written a lexer, where I use an FSM instead of regex to tokenize the input. I also have an enum for the different operators, which I use in place of the Token enum in expressions. It makes it a lot more verbose but also easier to reason about at least for me, notably a simple `if let` makes it trivial to check the kind of Expression for the instantiation parsing. Thanks for the series, and I hope you continue, I really like your way of explaining stuff and keeping the errors in makes it more relatable (and satisfying when I can spot bugs before you realize they exist) :)

Haha. The panic that comes about when I realize I made an error during recording is unmatched. I usually don't write any code beforehand or do more than one take so when I make.mkstakes you can hear the fear in my voice lmao. Glad you are doing it the Rust way. That's awesome to hear.

This is an amazing series. Keep it going. It's taken quite a while for me to follow this one since I've been quite busy with other projects but this one is as good as ever. Love your videos man can't wait for the next one. :)

instead of using reflection( which is slow ), you can simply use type assertion.. something like ` foo, ok := bar.(your_type)`

Must be nice being able to create stuff like this , can you guide me on what book to read

I don't know sadly. It was a cheap keyboard off Amazon. It was a red dragon I think.

Remember the creating your own programming language tutorial with JavaScript and TypeScript? Can you make a tutorial on how to have Deno make it somehow to work, yeah, like the apps you need to get for the playlist

Well the concept is the same for basically any language. For example I have write a nearly identical parser to this in C, C++, Zig, Rust, TS and of course Go. So you just need to translate the go Syntax to TS or whatever language you want. Then you can follow along without any issue even though we’re using different languages. If you have more questions reach out in my discord servers help thread. Cheers.
