What is the difference between type parameters and type inference?
An example of an AI chatbot conversation about type parameters and type inference in programming.
What is the difference between type parameters and type inference?
Type parameters are placeholders in generic programming that allow functions or classes to operate on different types. Type inference, on the other hand, is the ability of a programming language to automatically deduce the type of a variable based on the context.
Can you give me an example of type parameters?
Sure! In a generic function like function identity<T>(arg: T): T { return arg; }, T is a type parameter that can represent any type.
And how does type inference work in practice?
In TypeScript, if you write let x = 5;, the compiler infers that x is of type number without you needing to specify it.
Are there any advantages to using type parameters?
Yes, type parameters enhance code reusability and type safety, allowing you to write more flexible and maintainable code.
