What is the difference between type inference and type annotation?
An example of an AI chatbot conversation about type inference vs type annotation.
Can you explain the difference between type inference and type annotation?
Sure! Type inference is when the compiler automatically determines the type of a variable, while type annotation is when the programmer explicitly specifies the type.
Can you give me an example of each?
Of course! In Python, if you write x = 5, the type is inferred as an integer. In contrast, in TypeScript, you might write let y: string = 'hello'; which is a type annotation.
Why is type inference useful?
Type inference can make code cleaner and easier to read, as it reduces the amount of type information you need to write.
