Can you compile JavaScript?

JavaScript is an interpreted language, not a compiled language

compiled language

A compiled language is a programming language whose implementations are typically compilers (translators that generate machine code from source code), and not interpreters (step-by-step executors of source code, where no pre-runtime translation takes place).

Compiled language - Wikipedia

. A program such as C++ or Java needs to be compiled before it is run. The source code is passed through a program called a compiler, which translates it into bytecode that the machine understands and can execute.

Can JavaScript be compiled to native code?

It is certainly theoretically possible; however, a static compilation of JavaScript would need a very heavyweight runtime to support all of its features (such as dynamic typing and eval).

Can JavaScript be compiled to binary?

So Javascript is delivered as text, which is then interpreted and compiled by the browser. So if you're developing Javascript for the web, the answer is “no.” If you want to deliver cross-browser binaries, you'll need to look into WebAssembly, which is usually written in C/C++, Rust, or another language.
