Why is this showing I am not defined ?

Question

const obj1 = {name: kashyap};
const obj2 = {age: 120};

const tar = Object.assign({}, obj1, obj2);

console.log(tar);

// kashyap is not defined

Answer 1

{name: "kashyap"}
You need those quotes, otherwise it will search for a variable with the same name

Answer 2

It should be a String.
const obj1 = {name: 'kashyap'};
