So, with this chapter coming to an end, let's revise the topics we have covered so far.

We have seen the how jQuery has started taking shape and how it became a fundamental element of the modern-day web development. We have learned how to build basic jQuery documents and how to call the functions embedded into HTML files. We have learned why we started using deferred and promise in jQuery and how it helped us in achieving cutting-edge applications on both web -based platform and portable devices. We have seen saw many working examples to understand better and clear any doubts. The topic of promises in jQuery is huge, but we tried to summarize as much as we can to lay out solid foundations for those who hadn't used this property before and to help those who are already using it.

In the next chapter, we will see how all the combined JavaScript and their properties are shaping up to bring the world closer and making our life easier in the days to come.
