Object Interfaces
- Object Interfaces are used to define the shape or structure of an object.
- They define the properties with the types that an object should contain.
- We use the ‘interface‘ keyword to declare an object interface followed by the interface name and its properties.
- They can be implemented by other interfaces and classes, promoting code reusability and maintainability.
Example: This example shows the use of the TypeScript Interfaces.
Javascript
interface Employee { eid: string, name: string } const emp: Employee = { eid: "E54321", name: "Ravi"}; console.log(emp); |
Output:
{ eid: 'E54321', name: 'Ravi' }
