What are the differences between TypeScript and JavaScript in Angular?

What are the differences between TypeScript and JavaScript in Angular?

TypeScript is a superset of JavaScript that adds static typing, which helps catch errors at compile time. In Angular, TypeScript enhances code quality and maintainability.

Can you explain how TypeScript improves the development experience in Angular?

TypeScript provides features like interfaces, enums, and generics, which help in defining clear contracts and improving code readability. This leads to better tooling support and easier refactoring.

Are there any performance differences between using TypeScript and JavaScript in Angular?

Performance-wise, both compile down to JavaScript, so there isn't a significant difference. However, TypeScript's type checking can lead to fewer runtime errors, which can indirectly improve performance.

Is it possible to use JavaScript in an Angular project instead of TypeScript?

Yes, you can use JavaScript in Angular projects, but you'll miss out on the benefits of TypeScript, such as type safety and better tooling.
