Difference between Generics and Interfaces in TS
In TypeScript, generics and interfaces are two powerful features that can be used to write more reusable and maintainable code.
Generics are a way of creating reusable code components that can work with a variety of data types. They allow you to write functions, classes, and other constructs that can operate on a range of data types without being tied to a specific one. Generics are denoted by the angle brackets <>.
Here's an example of a generic function that takes an array of any type and returns the first element:
Interfaces, on the other hand, are a way of defining the structure of an object. They allow you to specify the shape of an object and its properties and methods, without actually creating an object. Interfaces are denoted by the interface keyword.
Here's an example of an interface that defines the structure of a person object:
You can also use interfaces to define functions that you want to use as a type:
