We know, TypeScript is a type of Object-Oriented JavaScript language and supports OOPs programming features like classes, interfaces, etc. Like Java, classes are the fundamental entities which are used to create reusable components. It is a group of objects which have common properties. A class is a template or blueprint for creating objects. It is a logical entity. The "class" keyword is used to declare a class in Typescript.
Example :
class Student {
studCode: number;
studName: string;
constructor(code: number, name: string) {
this.studName = name;
this.studCode = code;
}
getGrade() : string {
return "A+" ;
}
}​
Features of a class are :
* Inheritance
* Encapsulation
* Polymorphism
* Abstraction
