How can I modify objects in JavaScript?

You can modify objects in JavaScript using dot notation or bracket notation. For example, to change a property value, you can do obj.property = newValue.

Can you show me an example of adding a new property?

Sure! You can add a new property like this: obj.newProperty = 'value';. This will add newProperty to the object.

What about deleting a property?

To delete a property, you can use the delete operator: delete obj.propertyName;. This will remove the specified property from the object.

Is there a way to merge two objects?

Yes! You can use Object.assign(target, source) or the spread operator: const merged = {...obj1, ...obj2}; to merge two objects.
