Studies reveal that Java is one of the most popular programming languages used by developers.

This can be attributed to the fact that Java is widely used in industries such as financial services, Big Data, stock market, banking, retail, and Android. It is present everywhere! Whichever domain a developer works in, he/she will surely come across Java Programming.

An article by the Dev Community speaks about how Java is unarguably one of the most popular programming languages in the world today and how tech giants are using the language to build large portions of their infrastructure and backend services.

It makes a little more sense when you find out that the language was created at Mozilla, giving web developers a chance to write code that’s more performant than Ruby, PHP, JavaScript, or Python.

Common job roles requiring Rust

Some of the common jobs requiring Rust as a tech skill are:

  • Backend developers
  • Embedded system engineers

9. Django

Django is one of the most versatile and popular Python web frameworks that encourages rapid development and pragmatic, clean design of web applications. This can be attributed to Django’s open-source nature—the community is constantly releasing new code and plug-ins to simplify the process and keep up with the demand. It grabbed eyeballs right from the start when it was positioned as Python’s answer to Rails. 

Many Python development services, as well as major companies such as Spotify and YouTube, use Django. Developers describe it as “batteries included”, which means that it comes with a variety of third-party libraries. 

Django’s user base is expected to grow as more developers embrace Python for emerging technologies such as Machine Learning and Big Data. It is ridiculously fast, reassuringly secure, and exceedingly scalable. 

Note: We recommend using the latest version of Django, which is currently 3.0.2.
