Summary

In this chapter, we learned where JavaScript began and how it shaped into one of the leading technologies in modern application development. We discussed why there was a need for JavaScript in the early 90s and how this language has seen ups and downs throughout its existence.

We have also seen how investments from tech companies made their contributions in creating, developing, and evolving JavaScript as a major player in a dynamic and fast growing market of web, mobile, and real-time apps.

The adaptation of promises concept will make JavaScript much stronger and will help developers and engineers to write better code in an efficient manner.

In the next chapter, we will see what is an asynchronous model and how it's better fitted with JavaScript. This will help us understand to adopt and implement Promises.js in various languages.
