> Bun's unique choice of using JavascriptCore over V8 as its JS Engine, combined with Zig for internal implementation, promises superior performance and makes it a formidable NodeJS competitor. Exciting🚀🍏

> We all know it will take a long time for bun to replace node. It's like with react. There are so many better frameworks but you will always have the highest job guarantee with react because so many code bases are written in it.
