JavaScript[0] isn't what I would call a fast storage repository, but I guess it works out for prototyping.

On the context of porting to C and C++, or make it execute faster, I can see two options with minor rewrites.

Use AssemblyScript and generate native code via WebAssembly AOT compilers.

Try to adapt TypeScript to C++ compiler from Microsoft's MakeCode project.

Implement your own C++ code generator.

It would be much easier than keep using multiple code bases in parallel, plus any memory corruption issues would be most likely bugs on the code generator.

Indeed, TS/JS is great for its quick turnaround times for prototyping. But the I/O performance is executed by the underlying C/C++ layer. For the rest TS/JS is fast enough. But a full C++ backport is still on the horizon
