Why is npm install still so slow? The problem isnโt just JavaScriptโitโs the complexity of the layers in your stack. ๐๐ป Here is how compressing those layers changes everything.
Jarred Sumner, creator of Bun, explains the "Compressed Layers" architecture.
Discover why "shopping for libraries" kills productivity and how Bun moves essential I/O, SQL clients, and utilities directly into the runtime using native code and SIMD.
This is the engineering philosophy designed to replace the fragmented Node.js ecosystem with a single, high-performance toolkit.
