TypeScript
The default for any serious JavaScript project.
TypeScript is no longer optional for professional JavaScript development. The type system catches entire categories of bugs before they reach production, and the IDE experience — autocompletion, refactoring, inline documentation — makes developers measurably faster.
The adoption cost is near zero. TypeScript is a superset of JavaScript, so migration can be gradual. Every major framework, library, and tool supports it natively. The hiring pool understands it. The only remaining argument against TypeScript is for throwaway scripts — and even there, the setup cost is negligible.
