Can I use push and pop on objects?

Can I use push and pop methods on objects in JavaScript?

In JavaScript, push and pop are methods used with arrays, not objects. You can use them to add or remove elements from an array.

What if I want to add properties to an object?

To add properties to an object, you can simply assign a value to a new key, like this: obj.key = value;.

Can I use an array inside an object and then use push on that array?

Yes, you can have an array as a property of an object and use push on that array to add elements.

Can you show me an example?

Sure! Here's an example: let obj = { arr: [] }; obj.arr.push(1); console.log(obj); This will add 1 to the array inside the object.
