I’m old enough to remember when Javascript was primarily used to make something blink on your website. The days of blinky websites and AOL are long behind us. Javascript is now used throughout the tech stack. This heavy usage has exposed some warts. Overly complicated Javascript libraries have a tendency to introduce lots of latency.
Bun is a modern JavaScript runtime like Node or Deno focused on speed, and performance. It is an all-in-one tool (runtime, bundler, package manager, transpiler).
I haven’t spent a lot of time using Bun yet, but it is plenty impressive. They’ve done a nice job focusing on this being a “drop in” replacement for Node or Deno.
Take a look for yourself. I played with Bun and used Hassan’s article to mess around. https://www.thisdot.co/blog/a-look-at-bun-sh-the-modern-javascript-runtime
