A web developer needs to be smart and agile in their work. When something goes wrong in the development process, one cannot afford to start over with a project from scratch again.

That’s why it is essential to learn Version Control like Git and Github. This allows you to keep a consistent track of your development process so you can rollback to a previous version when something goes wrong. A full-stack web developer working on tight deadlines absolutely needs this skill.

3. Java 9-15

The JDK 9 brings a lot of goodies in terms of modules, Jigsaw, Reactive Streams, Process API, HTTP2 client, JShell, and API improvements like collection factory methods and I am really looking forward to learning them at the earliest opportunity.

Similarly, JDK 10 brings var to give you a flavor of dynamic typing and some GC improvement.

4. Spring Framework 5

As you can see, Spring is the most widely and popularly used framework. Now if you are looking for why its so, wait for it. Let me start by explaining a little about Spring.

Spring Framework is a powerful lightweight application development framework used for Enterprise Java (JEE).

The core features of the Spring Framework can be used in developing any Java application. It can be described as complete and modular framework.

The Spring Framework can be used for all layer implementations of a real time application. It can also be used for the development of particular layer of a real time application unlike Struts and Hibernate, but with Spring we can develop all layers.

5. Angular

These two JavaScript framework has completely changed how you develop web applications. In 2021, you have to learn Angular. Why? Simple, because Angular is easier.

The new Angular codebase is more modern, more capable and easier for new programmers to learn than AngularJS, while also being easier for project veterans to work with.

With AngularJS, programmers had to understand the differences between Controllers, Services, Factories, Providers and other concepts that could be confusing, especially for new programmers.


Technology changes with rapid speed, and the biggest challenge for programmers are to keep themselves up-to-date. So, you have to follow where technology lead the world.
