Bun is a JavaScript runtime, another alternative between: Nodejs, QuickJS, Deno and among others.

Although it is still in development, Bun is very successful due to its performance, accelerated flows and execution of simpler production codes in resource-limited environments, such as serverless functions.

Bun is a complete toolkit for JavaScript and TypeScript applications.

It was written in Zig and C++, drastically reducing startup time and memory usage.
