The performance of JavaScript can be a bottleneck, especially when it comes to running server-side code. That’s where Bun, one of the fastest JavaScript runtimes, comes into play.
What is Bun?
Bun is a fast, all-in-one toolkit for running, building, testing, and debugging JavaScript and TypeScript, from a single file to a full-stack application. Bun is an open-source! ❤
How fast is Bun.js?
Bun takes only 0.36 seconds to compile your code, whereas it takes about 6.44 seconds in the case of pnpm, 10.58 seconds with npm, and 12.08 seconds with yarn.
Why is Bun so fast?
Bun is fast because it uses the JavaScriptCore engine, while Node.js uses the JavaScript V8 engine. The former has been optimized for faster startup time.
