Deep cloning objects in JS used to require third-party libraries like Lodash or hacky JSON serialization that dropped Date objects, Map, Set, and RegExp. JavaScript const original = { user: "Joseph", joined: new Date, roles: new Set"admin", "d...

Relying on freeform text responses from LLMs in production breaks frontends when the model formats its response unpredictably or drops formatting tags. TypeScript // ✅ Force deterministic JSON schemas using structured outputs const response = await ...
