Hybrid type interfaces

Hybrid type interfaces are used when we want to use the object both as a function and an object. We can call an object like a function if it implements a hybrid type interface, or we can use it as an object and access its properties. This type of interface enables you to use an interface as an object and a function, as follows:

interface Customer { 
    (name: string); 
    name: string; 
    deleteCustomer(id: number): void; 
} 
  
var c: Customer; 
c('Rajesh Gunasundaram'); 
c.name = 'Rajesh Gunasundaram'; 
c.deleteCustomer(101);
