The Joy of Typescript
summary
Practical notes on adopting TypeScript: use Total TypeScript and a Code Snippets extension to read errors and scaffold interfaces, enable strictNullChecks, colocate types next to components or export shared types from a nearby file, avoid overusing "as" assertions, prefer union/intersection-heavy type declarations when you need composability and use interfaces when extension matters. Examples come from building multiple internal React services, where blue squiggly lines signal progress and DDD organization emerges from well-defined types.
