What are the differences between TypeScript and JavaScript modules?

What are the differences between TypeScript and JavaScript modules?

TypeScript modules are statically typed and provide better tooling support, while JavaScript modules are more flexible and dynamic.

Can you explain how imports work in both languages?

In TypeScript, you can use import { something } from './module'; for named imports, while JavaScript uses the same syntax but is more lenient with types.

Are there any performance differences when using modules?

Generally, performance differences are minimal, but TypeScript's type checking can catch errors at compile time, potentially reducing runtime errors.

What about module resolution in TypeScript?

TypeScript has a more complex module resolution strategy, allowing for custom paths and aliases, which can simplify imports.

Can I use JavaScript modules in a TypeScript project?

Yes, TypeScript can seamlessly integrate JavaScript modules, allowing you to gradually adopt TypeScript in your projects.
