While plenty of educational material exists for beginning and advanced jаvascript developers, resources for intermediate-level engineers are scarce. Yet this is the career step where many developers often get stuck. With this practical book, you'll learn how to apply jаvascript theory in real projects, manage every stage of the software development lifecycle, and move your career forward.

Author Milecia McGregor takes frontend, backend, and full stack engineers through all of the steps and considerations of senior jаvascript engineers, including making decisions based on product and user feedback. By the time you finish this book, you'll know how to create a production-level app for any size system you face.

You’re likely already familiar with a lot of concepts in jаvascript. Things like the different array methods and how to use them, DRY principles, and writing effecient code. These are all important to a jаvascript developer at any level. While it’s great to be familiar and comfortable with those concepts, there are a few things that take you deeper into jаvascript and might help you understand how and why we write code the way we do. In this chapter, we’ll spend some time on more advanced jаvascript concepts. You probably work with these all the time and so some of them will be familiar. Others might have never come up in your day to day programming tasks, even though they’re always in the background.

One big complaint in the jаvascript community is that it is a weakly-typed language. In jаvascript, your variables can be anything at anytime. This leads to issues with values dynamically changing while an app is running which can lead to unexpected errors, causing your applications to crash for users. That’s where TypeScript comes in. TypeScript is a language developed by Microsoft that’s an extension of jаvascript that adds the ability to use types. It can be used on the front-end and the back-end, regardless of any frameworks you choose to work with.
