TypeScript is an programming language which has been developed by Microsoft which compiles to JavaScript. It is open-source. TypeScript is a superset of JavaScript as it adds static type definitions. It helps developers to develop scalable and reliable applications for web and mobile. It offers interfaces, classes, and generics under object-oriented programming support. The features it adds to JavaScript makes JavaScript to be more flexible and scalable.
