How do TypeScript and JavaScript compare in terms of performance?

How do TypeScript and JavaScript compare in terms of performance?

TypeScript is a superset of JavaScript, so its performance is generally similar. However, TypeScript's static typing can lead to better optimization during development.

Does TypeScript add any overhead that affects performance?

Yes, TypeScript can introduce some overhead during the compilation process, but the runtime performance is usually comparable to JavaScript.

In what scenarios would TypeScript perform better?

TypeScript can perform better in large codebases where type checking helps catch errors early, leading to more efficient code.

Are there any benchmarks comparing their performance?

Yes, various benchmarks show that while TypeScript may have a slight overhead during compilation, the runtime performance is often on par with JavaScript.
