The creation of an object, as we have seen in the examples, is quite straightforward using the literal notation. We do not have to define a class, but we directly create the object just when we need it, and hopefully we can change its structure during the execution of our script.

Suppose, we need multiple objects of the same type, for example more person objects, which share the same structure.

Using the literal notation, we will have to repeat the definition for each object that we want to create, which is essential to identify the single person but unnecessarily repetitive for constant members such as the methods. In other words, using the literal notation in the definition of the objects, we get a non reusable result. For ...
