Episode notes
Essence of TypeScript
- TypeScript is a weird yet practical language compiling to JavaScript with a unique type system.
- It features structural, static, strong, mostly inferred, gradually typed characteristics.
Why Compile-to-JS Languages Exist
- JavaScript's huge ubiquity led to big apps but lacks essential features for scalability.
- Many compiled-to-JS languages, like TypeScript, address JavaScript's shortcomings by adding static types.
Heed TypeScript Errors Early
- Pay close attention to TypeScript errors shown as red squigglies in your editor as you type.
- Fix type errors promptly to strengthen code safety and prevent bugs before compilation.
