Node.js and Deno Competitor: Bun

Technology is evolving so fast because of a phenomenon known as Accelerating Change.

A new and modern JavaScript runtime like Node or Deno is Bun. Its main focus is on being faster, the next level of performance (because it uses the JavaScript Core, not V8), and a comprehensive tool (bundler, transpiler, task runner, package manager npm built-in).

Why Bun is Fast?

• It’s written in Zig which is a low-level programming language with cross-compilation and manual memory management.

• Its team spent a lot of time profiling, benchmarking, and optimizing everything.

In an example from Bun, below are the rendering requests per second:

Also, Its installation is very smooth and fast than Node or Deno.

Should You Use Bun in your Next Project?

Well, most likely not. It is still in beta mode and not ready for production. They are fixing bugs reported by users and making it ready for production But it’s probably important to keep an eye on, and worth giving it a test and try.

You can view the source code of Bun on Github.
