What is the difference between type inference and explicit types in programming?

What is the difference between type inference and explicit types in programming?

Type inference allows the compiler to automatically deduce the type of a variable, while explicit types require the programmer to specify the type.

Can you give me an example of each?

Sure! In TypeScript, let x = 5; uses type inference (x is inferred as a number), while let y: number = 10; is an explicit type.

What are the advantages of using type inference?

Type inference can lead to cleaner code and reduce redundancy, making it easier to read and maintain.

Are there any downsides to type inference?

Yes, type inference can sometimes lead to less clarity, especially in complex code, making it harder to understand the intended types.
