The rapid development of the IT industry has led to the emergence of new professions for which institutes have not yet had time to prepare curricula and teachers. Not only familiar specializations are becoming irrelevant, but also some areas of IT. How to choose what will be in trend for a long time and will not give up its positions, not to miss and make your entry into the profession successful, we asked five seniors and compiled a TOP of technologies where you can safely go in 2021 and be confident in the prospects.

Numbers in order, not by importance

- After 2020, the question of choosing a profession is perhaps more relevant than ever. And it's not just about progress: the Covid-19 pandemic has seriously affected the labor market, with employment falling in many areas. Web development is social media marketing service one of those global industries that moved forward in 2020. Interfaces are becoming more complex year after year, and the IT sector needs advanced specialists who can understand all the nuances.

JavaScript is one of the most widely used languages , which has practically become a standard in web applications. It has a rich ecosystem with an abundance of frameworks, libraries, and other tools, as well as a huge community of developers.

In the foreseeable future, it is almost impossible to displace JavaScript from the leading positions in web development. The largest number of vacancies can be seen for the position of a frontend developer ( according to dev.by ). What other arguments are needed?

Indeed, JS looks like a very profitable entry point, but what about Java?

Ekaterina Milashevskaya, Java developer at SoftTeco

- Java is a flexible and predictable language in high-load systems. It is built like no other to work on multi-core machines, and you can write an application on a regular computer, and it will then work well on a multi-core processor of a powerful server in the cloud, using it as rationally as possible. Another important point: all Java applications work in their own JVM environment, which can be installed on any operating system (OS). This is a cross-platform language with the most time-tested performance in any OS. Many creators of new languages ​​liked this principle so much that they took JVM as a basis for their virtual machines. Java has also proven itself in programming on microchips: the most familiar devices for us are our smartphones, in particular, Android. The popular Blu-Ray video format is also based on Java, so any additions or "hacks" for such discs can be made by any Java programmer if desired. Java also remains a strictly typed language with high requirements for the code structure: all brackets, quotes and commas must be in place, although most languages ​​have moved away from this and simplified the syntax as much as possible. They do not have strict requirements for specifying the type: they are recognized by the compiler. But personally, I have a positive attitude towards the typing of our language: it still adds confidence that during the execution of the program everything will be understood correctly everywhere, and the application will work correctly.
It's unbelievable, but true:

Everyone's favorite Minecraft is written in Java. And it's also one of the few languages ​​where with the arrival of a new version you don't have to rewrite half the project, because a sea of ​​libraries have changed and the new ones have a completely different structure.
