About this Episode

TypeScript might feel slow, but is it really? In this episode, Mike Hartington DevRel at Nx joins us fresh off his React Miami talk to unpack what actually causes TypeScript slowdowns in large monorepos, and how techniques like project references, workspaces, and precompiled DTS files can supercharge your dev experience. We also dig into the upcoming Go-based TypeScript compiler and how it could deliver 10x+ performance gains.
