What are some examples of type inference in programming?

Type inference is when a programming language automatically deduces the type of a variable. For example, in Python, if you write x = 10, Python infers that x is an integer.

Can you give me more examples in different languages?

Sure! In JavaScript, if you declare let name = 'Alice';, the engine infers that name is a string. In TypeScript, you can use let age = 25; and it infers that age is a number.

What are the benefits of type inference?

Type inference can make code cleaner and easier to read, as you don't have to explicitly declare types. It also helps catch errors at compile time.

Are there any languages that don't support type inference?

Yes, some languages like Java require explicit type declarations, although newer versions have introduced some type inference features.
