Apr 23, 2022 · Javascript is about 10 to 100 time slower and on top of that it is single-threaded. Generally it doesn't matter at all, if you want to manipulate a web page you go Javascript anyway. If you really need more speed and you're not in a browser you go C++.

If your app has performance critical parts, should you stay in JavaScript? Or write a native C++ addon? Or use WebAssembly? Let's have a look at how these options compare performance wise and which one is best for different workloads. So the next time you need to optimize for speed, you know your options.
