Bun looks interesting! Finally a javascript runtime which does NOT use Chromiums V8 engine (it uses Webkits JavaScriptCore)!

bun.sh/

It is still in early development, but the project goals look promising! This is worth keeping an eye on.

@puresick It describes itself as a JS engine, but runs on JavaScriptCore which is a JS engine... can you explain?

@schnittchen Where did you read that?

I am only seeing it describes itself as "JavaScript runtime" which uses the "JavaScriptCore engine".

@puresick oh sorry, my brain merged the two together. Actually I don't understand the difference

@schnittchen No worries! :)

Roughly explained:

The engine is what translates/compiles/interprets JavaScript into instructions for a computer to execute. This is the part which is implemented in most internet browsers and necessary to run JavaScript code.

The/a JavaScript runtime (like bun, nodejs or deno) basically wraps the engine into an executable which offers some high level functionality, abstractions and APIs to work with.

@puresick so the runtime is like an executable wrapper plus stuff like filesystem API?

@puresick @schnittchen I follow Jarred Sumner (twitter.com/jarredsumner), he’s definitely full speed with the development of Bun since months, it’s crazy.
