What are some examples of merging objects in JavaScript?

Can you show me some examples of how to merge objects in JavaScript?

Sure! One common way to merge objects is using the Object.assign() method. For example:

const obj1 = { a: 1, b: 2 };
const obj2 = { b: 3, c: 4 };
const merged = Object.assign({}, obj1, obj2);
console.log(merged); // { a: 1, b: 3, c: 4 }

What about using the spread operator?

Great question! You can also use the spread operator to merge objects. Here's how:

const obj1 = { a: 1, b: 2 };
const obj2 = { b: 3, c: 4 };
const merged = {...obj1, ...obj2};
console.log(merged); // { a: 1, b: 3, c: 4 }

Are there any differences between Object.assign and the spread operator?

Yes, there are some differences. Object.assign() mutates the target object if provided, while the spread operator creates a new object. Also, Object.assign() can only merge enumerable properties, whereas the spread operator can handle more cases.
