Deleting Properties

Lecture 148:- Deleting Properties

In JavaScript, you can delete properties from an object using the delete keyword. Here's the syntax:

arduinoCopy code

delete objectName.propertyName;

Here, objectName is the name of the object from which you want to delete the property, and propertyName is the name of the property you want to delete.

For example, let's say you have an object called person with properties name, age, and gender. To delete the age property from this object, you can do:

arduinoCopy code

delete person.age;

After executing this code, the person object will no longer have the age property.

It's important to note that deleting a property from an object does not change the order of the remaining properties, and does not affect the length of the object. It simply removes the property from the object.
