Bun, it seems to be everywhere nowadays, is it worth the hype or it will fade away just like deno did, let's have a deeper look shall we.
The Good Parts
It's fast, ...really fast
While bun has a lots of nice features, the greatest one so far is the performance it offers, the biggest difference that bun has compared to nodejs under the hood is the JavaScript engine that they are using.
NodeJS is build on the trust V8 engine, which is a pretty good engine, but the Bun team decided to go ahead with JavaScriptCore given it's way faster and memory efficient compared to the v8 engine.
Excellent TypeScript Support
Adding TypeScript to your application is easy but it's still a hassle you need to take care of, with Bun we get "Native" TypeScript support, heck you can even import a typescript file into a javascript file without doing any sort of transpiling.
It's also a Bundler
Bun has a bundler built in (I know, shocking) and guess what it's faster than webpack, it also has several plugins for loading files for scss, json, toml and much more.
New Native Libraries (yay!)
Bun has an HTTP server built into it, after some testing I can say it's all right which is faster than express, it also has saveral libraries for Worker, File I/O, Hashing and much more but what really blew my mind was the inclusion of WebSockets, with bun implementing that will be easier than ever.
SQLite, Really?
Yes, you heard it right, it's has support for SQLite databases natively built into the runtime, it could be a real Boon(no pun intended) when you are working on small localized applications.
Closing Remarks
Given all the points above, bun is a promising candidate to replace NodeJS, but only time will tell.
