TypeScript – JavaScript for C# devs
summary
Claims that adding static typing and classes gives real IntelliSense and fewer runtime errors, then demonstrates a working browser app: a Spotify searcher built in TypeScript, compiled by tsc/Visual Studio, using fetch (with @types), async/await, modules and a small HTTP service abstraction, and loaded with SystemJS. Shows practical fixes: add lib entries to tsconfig, install @types/fetch, enable compileOnSave, and that the app runs after those changes, improving navigation, squiggles and maintainability.
