What's next: From Node to production
Three follow-ups, ranked by how much each extends what you built.
Path 1: Cluster across N processes with node:cluster. Throughput multiplies by core count. This is how production Node services use multiple CPUs.
Path 2: Port the workshop to TypeScript. Define a typed RESPValue, get compile-time checks on every dispatch handler. Probably 200 lines of changes total.
Matching exercise: Match the workshop primitive to the real-Redis equivalent

Path 3: Read node-redis or ioredis source code. You can now navigate them because you have written the server side of the same protocol.
