You may be a fan of everything the bun team is doing, and yes, @jarredsumner had done some amazing work. But take notice, one thing Jarred and Bun has never done is try to dunk on Node.js developers or be disrespectful to the project. That's very important and appreciated...

The implementation of bun install is hard mode. Nearly everything is linearly serializable. We avoid pointers because arrays might resize causing an invalid pointer, so we use byte offsets into a single buffer and a “string builder” to count then allocate then append
