What is difference between interface and class in TypeScript?

// That said, we recommend you use interfaces over type aliases . Specifically, because you will get better error messages. If you hover over the following errors, you can see how TypeScript can provide terser and more focused messages when working with interfaces like Chicken.

In TypeScript, an interface is an abstract type that tells the compiler which property names a given object can have . TypeScript creates implicit interfaces when you define an object with properties. It starts by looking at the object’s property name and data type using TypeScript’s type inference abilities.

Step 1: Create your model using “Classes” . While TypeScript has interfaces that can provide this functionality, the Angular team recommends just using a bare ES6 class with strongly typed instance variables.

Classes are the fundamental entities used to create reusable components. It is a group of objects which have common properties. It can contain properties like fields, methods, constructors, etc. An Interface defines a structure which acts as a contract in our application.
