Is WebAssembly the future?

According to Firefox’s Lin Clark, future features will include multithreading, SIMD support, and improved compilation.

Is Python better than JavaScript?

What is the point of WebAssembly?

WebAssembly is a new type of code that can be run in modern web browsers and provides new features and major gains in performance. It is not primarily intended to be written by hand, rather it is designed to be an effective compilation target for low-level source languages like C, C++, Rust, etc.

Is JavaScript faster than C++?

C++ vs JavaScript: Performance C++ is ten or more times faster than JavaScript across the board. There is no argument which is faster.
