*Interface is nothing, you only have to use 'interface' keyword in place of 'type' like what we've done in "type Alises". Also we don't need to use any equal to sign (=) and BOOM that's it!! It acts very similar to type Alises but just a newer version of it.*

// interface => same as type alias => used for specificying the data types of objects (intoduced in newer version of TS)
// always use ; not,
interface personDT {
name:string;
age:number;
city:string;
}

const person1:personDT = {
name:"Hemant",
age:24,
city:"Chhatarpur"
}

function greet1(person:personDT){
console.log("Hello, " + person.name);
}

greet1(person1);


//

interface Product {
name:string;
price:number;
quantity:number;
}

const product1:Product = {name:"pencil", price:5, quantity:5}


function calculateTotalPrice (product:Product):number {
return product.price * product.quantity;
}

[zakidev]

interface Product {
name: string;
price: number;
quantity: number;
}

const myProduct: Product = {
name: "Laptop",
price: 1899,
quantity: 3
}


function calculateTotalPrice(product: Product): number {
return product.price * product.quantity;
}
