Jaithon 3: A Fast Language with the Perfect Syntax
Jaithon 3, a fast programming language with the perfect syntax
Jaithon 3 is a dynamically executed, garbage-collected language with a bytecode VM, drawing architecture from Java and syntax from Rust and Python. It is heavily bootstrapped, with most features written in Jaithon itself. The project leverages AI-assisted coding (about 80% of raw code) while maintaining human oversight for design and architecture. It includes a REPL, formatter, type checker, and packages like jaiplot and jaitensor for GPU-accelerated ML.
Without agentic coding, Jaithon 3 probably wouldn't have existed, and Jaithon would have been stuck at a primal level.

First impression: looks more like JavaScript than Python?

Hi HN! I’m Abhirama, and I started Jaithon in 2023 when I was in 8th grade to teach myself how to code in C. Jaithon 1 was really bad, it was all in one file and it was completely an interpreter and it was extremely slow with bugs everywhere. Recently, I have came back to this project with the goal of making the perfect programming language that is not only fast, but it has the optimal syntax & features out of every programming language.
Jaithon has Python features such as comprehensions, f-strings and first-class functions with declared fields, explicit visibility, traits and checked type annotations, along with syntax choices from lua, Java, bash, c++, go, and rust.
The compiler separates lexing, parsing, type checking and bytecode generation. The VM has 107 opcodes along with a JIT compiler to speed stuff up, polymorphic inline caches and a garbage collector.
Jaithon is nearly completely bootstrapped, with the lexer, parser, and bytecode generation built completely within Jaithon itself. The syntax of jaithon code is also easily customizable.
You can build and run it with:
git clone https://github.com/abhiramasonny/jaithon
cd jaithon
make
./jaithon examples/hello.jai
It would mean a lot if you star the project on my GH as I am trying to reach 15 stars soon :) anyways, lmk if you have any feedback. Currently Jaithon is between Java and C++ for speed (a more detailed benchmark exists within the project by running make benchmark) and I am in the process of optimizing the VM. […]

Nice! This is what I keep telling everyone: LLMs let you build stuff you may not have the time/energy to before. You still need to do the last 10% yourself though. Tying up all the loose ends.
Syntax is a personal choice. Can always be changed. Architectural choices are difficult to manage later on.
The VM seems to be a stack VM. I have my own python replacement project (https://news.ycombinator.com/item?id=48090665) that I am developing privately for now. LLM-assisted ofc. Started with a bytecode VM and then switched over to a register one. The biggest break from regular language systems was the decision to move to an Erlang-style preemptive scheduler.
