Bun - the new Javascript runtime has just announced its first beta release and makes the claimed that it's significantly faster than Node and Deno, not just a little bit faster, but orders of magnitude faster. What makes Bun special?
Performance ⚡
It doesn't use the V8 engine but instead uses the JavaScriptCore from WebKit which is generally considered to be faster. In addition it's written in a low level programming language called ZIG that similar to C or Rust and the creator of Bun say ZIG the lack of hidden control flow makes it much simpler to write fast software.
All-IN-ONE Runtime 🎁
- Native module bundler to replace tools like Webpack.
- Native transpiler to support Typescript code out of the box.
- Top level await (just like Deno🦖)
- Auto transpile JSX files
- Supports WebAPI like
fetch,WebSocketandReadableStream - Supports many Node core modules as well as Node API which will allow many NPM packages also work in Bun.
- Implements Node.js' module resolution algorithm, means you can install packages from npm into bun and those packages install 20x faster.⚡😲
- Environment variables load automatically, no more
dotenv. - Native test runner like Jest.
Try it out, if you are using Windows, you are required to use WSL to install Bun.
Thank you for reading.

Agree, but if the performance do matters for the existing projects, then it is worth to do so. 😁
And what an excellent project requires is an Awesome page 😄

PS: Bun is awesome (breath of fresh air) and I believe it will force the competition to also invest in performance.
Just-JS - Why is Javascript in the top 2 of techempower?
With a native bundler, transpiler, task runner, and NPM client built-in; it's a breath of fresh air.
Great. This is awesome
