What are some real-world examples of type inference?

Type inference is used in languages like TypeScript and Scala. For instance, in TypeScript, if you declare a variable without a type, the compiler infers it based on the assigned value.

Can you give me a specific code example?

Sure! In TypeScript:

let num = 42; // TypeScript infers 'num' as 'number'
let str = 'Hello'; // 'str' is inferred as 'string'

What are the benefits of using type inference?

Type inference reduces the need for explicit type annotations, making code cleaner and easier to read while still providing type safety.

Are there any drawbacks to type inference?

Yes, one drawback is that it can sometimes lead to less clear code, especially for complex types, making it harder for others to understand the intended type.
