The TypeScript Tax

Developer Tooling: My favorite feature of TypeScript, and arguably the most powerful practical benefit from using TypeScript is its ability to reduce the cognitive load of developers by providing interface type hints and catch potential errors in realtime as you’re programming. Native JavaScript autocomplete and error detection gets you 80% — 90% of the benefits of TypeScript when you use autocomplete, type inference, and lint tooling. Example of Native JavaScript Autocomplete with Type InferenceIn fairness, if you use default parameters to provide type hints, you don’t need to supply the annotations for TypeScript code, either, which is a great trick to reduce type syntax overhead — one of the overhead costs of using TypeScript.
