In JavaScript, objects can be seen as a collection of properties. With the object literal syntax , a limited set of properties are initialized; then properties can be added and removed. Property values can be values of any type, including other objects, which enables building complex data structures. Properties are identified using key values. A key value is either a String value or a Symbol value .
There are two types of object properties: The data property and the accessor property .
Note: It's important to recognize it's accessor property — not accessor method . We can give a JavaScript object class-like accessors by using a function as a value — but that doesn't make the object a class.
