What are TypeScript typings and how do I use them?

TypeScript typings are a way to define the shape of data in TypeScript. They help with type checking and provide better tooling.

Can you give me an example of how to define a typing for an object?

Sure! You can define a typing for an object like this: interface User { name: string; age: number; }.

How do I use these typings in a function?

You can use the typings in a function by specifying the type of the parameter, like this: function greet(user: User) { return Hello, ${user.name}; }.

What if I want to use a third-party library without typings?

You can use the @types package for that library or create a custom typing file to define the types you need.
