How does type inference improve code quality?

What is type inference and how does it work?

Type inference is a feature in programming languages that automatically deduces the type of a variable based on its value. This helps reduce the need for explicit type declarations.

How does type inference improve code quality?

Type inference improves code quality by reducing errors, enhancing readability, and allowing for more concise code. It helps developers focus on logic rather than type management.

Can you give an example of type inference in action?

Sure! In languages like TypeScript, if you write let x = 5;, the compiler infers that x is a number, so you don't need to specify it explicitly.

Are there any downsides to type inference?

Yes, while type inference can simplify code, it may also lead to less clarity in some cases, making it harder to understand the intended types without explicit declarations.
