js2cpp

Intro

js2cpp is a compiler for converting JavaScript to C++.
In comparison with some other projects like QuickJS compiler, js2cpp generates no-overhead C++ code that can be compiled.
js2cpp is currently an Alpha quality compiler.
This means that js2cpp is under heavy development and you have to be ready to encounter some problems.
Different things may not work well.
For more information see STATUS file.

Usage

It's very easy. You need to run node js2cpp.js your_js_file and you'll get file js_result.cpp.

In

let a = 'Hello world';
console.log(a);

Out

//Auto generated code using js2cpp
#include <iostream>
#include "src/stdlib/builtins.h"
#include "src/stdlib/console.h"
using namespace std;
int main(){
JS_string a = "Hello world";
console.log(a);
return 0;
}

It can be compiled using C++ compiler like g++ (for details see this page).
