What are some examples of using Object.assign in JavaScript?

Can you give me some examples of how to use Object.assign in JavaScript?

Sure! Object.assign is used to copy the values of all enumerable properties from one or more source objects to a target object. Here's a basic example:

const target = {};
const source = { a: 1, b: 2 };
Object.assign(target, source);
console.log(target); // { a: 1, b: 2 }

What happens if there are properties with the same name?

If there are properties with the same name, the values from the source objects will overwrite the values in the target object. For example:

const target = { a: 1 };
const source = { a: 2, b: 3 };
Object.assign(target, source);
console.log(target); // { a: 2, b: 3 }

Can I use Object.assign to merge multiple objects?

Yes, you can merge multiple objects! Just pass them as additional arguments. For example:

const obj1 = { a: 1 };
const obj2 = { b: 2 };
const obj3 = { c: 3 };
const merged = Object.assign({}, obj1, obj2, obj3);
console.log(merged); // { a: 1, b: 2, c: 3 }
