Mastering Back-End Development - Stage 4: More On JS

3 min read

After learning the basics of computer science and the JavaScript ecosystem, and generally exploring, it's finally time to invest heavily in JavaScript. This investment will be rewarding in terms of the skills you will gain and the value it will add to you as a web developer and to your resume as a job seeker.

We are going to build a solid knowledge in JavaScript so that in the future you won't have skill issues. This will help you learn the technology and frameworks faster and more deeply.

Object oriented programming in JavaScript

Before we dive into implementing object-oriented principles in JavaScript, we need to understand what it is. To do so, please watch the following videos:

Since OOP is widely used in the industry and can be a bit complicated, feel free to explore more about it and ask question. here is a list of useful videos

After you did your researches get back to the track and start learning from the following resource.

After you read through these resources, please consider watching the following videos as well. They are great for learning and practicing the harder and more complicated parts of OOP:

OOP programming is a broad and extensive subject. Keep in mind that we will return for more in-depth learning about this topic. For now, what we have learned here is more than enough for the foreseeable future.

Debugging and error handling

Well, shit happens, prod environment will break, database tables will drop. and there is always a developer who needs to fix the issue and save the day. Besides that, we need to be prepared for unexpected errors and bugs. We have to anticipate potential issues and put safeguards in place so that, in case of an emergency, we don't overwhelm the system and break it.

Promises, Event Loops, Modules

These concepts are fundamental to asynchronous programming in JavaScript, which is essential for building responsive and efficient back-end applications. You'll learn how to work with promises, understand the event loop, and organize your code using modules.

Modules

💡
Asynchronicity is a very important topic in web development. Please give it more attention because what you learn now will determine how far you can go. Please don’t move on to the next steps without a deep understanding of asynchronous programming.

Typescript

TypeScript is a superset of JavaScript that adds static typing. You'll learn the benefits of using TypeScript, its syntax, and how it can improve your code quality and maintainability. For now, we won't spend a lot of time learning TypeScript, but we will definitely return to this topic later to explore it further.

JavaScript Run Times

Understanding how JavaScript actually runs is key to writing efficient code.
