If you want to process Javascript outside of the browser you can use
node.js and other
V8 engines.
Node.js is a JavaScript runtime built on
Chrome's V8 JavaScript engine.

V8 is Google's open source high-performance JavaScript and WebAssembly engine, written in C++. It is used in Chrome and in Node.js, among others. It implements ECMAScript and WebAssembly, and runs on Windows 7 or later, macOS 10.12+, and Linux systems that use x64, IA-32, ARM, or MIPS processors. V8 can run standalone, or can be embedded into any C++ application.

It is best known as the language embedded in web browsers but has also been widely adopted for server and embedded applications.

preted JavaScript scripts run in Rhino. Note that this debugger will not work with JavaScript scripts run in the mozilla browser since
Rhino is not the engine used in such environments.

-f script_filename_or_url
Reads script_filename_or_url content and execute it as a JavaScript script.
-opt, -O optLevel
