Structuring the application is a really important part. If we look at the code we have written, we can see that it does not have a good structure. The structure has to be such that in the future if we want add some features to it, it should be easy to do so. And code should be written in such a way that it is easily maintainable. To achieve this, we need to use some sort of a structure, which is called a framework. Frameworks are designed to give a sense of structure to the application.
