So what exactly is Bun.js and how does it impact the JavaScript ecosystem?

What is Bun.js?

Bun.js is an “all-in-one” JavaScript runtime that is classified as very fast. Bun.js is the third JavaScript runtime after its two predecessors, Node.js and Deno.js, which was created by Jarred Sumner using the Zig programming language.

The main goal of its creation was to provide a platform mali email list for running JavaScript outside the browser like Node.js and Deno.js, but Bun advanced to provide new levels of speed and increased complexity.

Bun.js is built with a focus on three things, namely:

Quick start (speed in running programs).
New performance improvements (extending JavaScriptCore).
Bun.js uses the JavaScriptCore engine, which tends to start and perform tasks a little faster than traditional options like V8. Quoted from the official website , Bun.js is written in a low-level programming language with manual memory management. Most of the Bun framework is written from scratch including the JSX/TypeScript transpiler , npm client, bundler, WebSocket client and more.
