Objects

JavaScript Object is a unique entity, which can contain named values and functions.
Unique means that, each object is treated as an individual entity, thus, when you compare two objects with the same contents, compiler will show that they are different. Properties can be any kind of data: string, number, boolean, array, and even an object. You can nest objects inside other objects.
You can easily access properties in two ways: with a dot, or with square brackets. This will return object's property value. If you want to access methods in an object, you can only access them with a dot. This way you're able to use functions of an object.
To add properties to an existing object, access the object with a dot or square brackets, type property name, and assign it with a value. In case of adding functions, you can only access the object with a dot.
To change value of an object property, the process is very similar to adding properties, but you need to access existing properties.
To delete properties, use delete function, and call the property of an object, or method you want to delete.
