How to implement Dynamic binding using the Salesforce lightning component?

Welcome back All, here we will learn about the dynamic field of Lightning Component. As Most of you must be aware of that In Lightning, Component Dynamic component is not available. Recently I was working on one of my projects and implemented the Dynamic binding using the lightning component so I am going to share how I implemented the same so that it may help others.

As we all know that we can use the Dynamic Binding in the VisualForce page but in Lightning Component it is not Possible.

In this example, We will show the list of Objects in a picklist and when user will select any object it will dynamically show the TOP 15 records in a table.
