What is the difference between explicit and inferred types?

Can you explain the difference between explicit and inferred types in programming?

Sure! Explicit types are defined by the programmer, while inferred types are determined by the compiler based on the assigned value.

Can you give me an example of each?

Of course! In TypeScript, an explicit type would be: let num: number = 5;. An inferred type would be: let num = 5; where the type is inferred as number.

Why would I use explicit types instead of inferred types?

Using explicit types can improve code readability and help catch errors early, especially in complex codebases.

Are there any downsides to using explicit types?

Yes, it can lead to more verbose code and may require more maintenance if types change frequently.
