There are a few compilers that translate JavaScript and TypeScript to C:
- QuickJS compiles JavaScript to C using an embedded JavaScript engine. This implementation is fairly complete, unlike the other compilers listed here.
- ts2c translates JavaScript and TypeScript source code to C, but it only supports a small subset of JavaScript's features.
- NectarJS compiles a subset of JavaScript to C or WebAssembly.
Similarly, it may be possible to compile some statically-typed JavaScript programs to WebAssembly using AssemblyScript, and then decompile them to C using wasm2c.
Alternatively, it might be possible to compile JavaScript to another language that compiles to C:
- Compile JavaScript to Python, and then compile Python to C using Cython or RPython. Since these compilers are compatible with a subset of Python, this should allow a subset of JavaScript to be translated to C.
- Compile JavaScript to Lua using Castl, and then translate the Lua code to C using lua2c.

JavaScript to C: Can you do this without an online code translator/converter?
Why would you want to. The code translate is by far the easiest was to go. Javascript has a simple and well-defined syntax and not hard to write a simple parser to extract. More on reddit.com

Very, very tricky --- Javascript is a heavily dynamic language where pretty much everything can be changed at run time: names of variables, functions, types, etc. As such it maps very badly onto C. And that's not even considering eval(), which will let you construct arbitrary chunks of Javascript in strings and run them.
Any Javascript translator would have to be able to cope with such things, which means it would have to translate the Javascript into C at run-time --- which makes it a JIT, which you're already using.
You may want to look at writing C bindings for Javascript instead. These will allow your Javascript code to call out to C code and vice versa. This would allow people to write plugins in C, compile them into .so shared libraries, which you can now load and run from your Javascript code. This means you don't need to translate anything.
Javascript's not my area so I can't recommend any particular mechanism, I'm afraid --- but I'd be very surprised if V8Juice, which you've already found, didn't let you do this.

Source-to-source code translation from JavaScript using AI involves utilizing natural language processing (NLP) techniques and machine learning algorithms to analyze and understand source code
And spits out C that works when compiled to achieve the same result (minus dynamic arguments passing) as JavaScript.
How would you go about achieving this locally?

Translating JavaScript source code into other programming languages · Issue #16 · timothycrosley/jiphy
January 8, 2016 - Jiphy is an excellent tool for translating Python source code into JavaScript and vice-versa, but it doesn't appear to generate code in other languages yet. I think we could make this translator more versatile since my own Transpiler-generator system can translate JavaScript and Java code into Ruby and several other programming languages.

September 18, 2024 - From compression to cryptography to networking to the web browser you're reading this on, the world runs on C. If it's not written in C, it speaks the C ABI (C++, Rust, Zig, etc) and is available as a C library. C and the C ABI are the past, present, and future of systems programming. That's why in Bun v1.1.28, we introduced experimental support for compiling and running native C from JavaScript
