The IT sphere is developing every day. If you want to change your specialty, this is a direction in which it is easier for newcomers to start in the market.

Popularity of programming languages
There are already 8000 programming languages invented. The importance and popularity of individual types changes all the time. A programming language is a set of rules for creating a program.

There is a popularity rating for languages in programming and a good programmer checks for relevance in order to objectively assess the result of the effort spent. Popular platforms for rating analytics are:

TIOBE Index.
Stack Overflow.
GitHub.
TIOBE Index.

The ranking is based on the results of search queries in which the name of the language is specified. If a language is frequently found in search engines, it means that it is used by a large number of programmers and is relevant. But this can be a controversial argument, because an experienced professional is unlikely to search for a language by name. He will be interested in solving a specific problem.

This rating is in demand because it shows popular programming languages and information is constantly updated.

Stack Overflow is a service for IT-specialists, where interaction takes place on a question-and-answer basis. And it is a knowledge base with which it is possible to solve a problem.

The service allows you to create a personal profile with a description of work experience. And it is used by recruiters if they are looking for a candidate for a particular job. You can read the chain of discussions in which a particular user participated and get to know him in detail, understand his interests and requests.

GitHub
GitHub is a cloud platform for hosting IT projects and collaborative development. In addition, it is a full-fledged social network for developers. Here you can find a project in any language and take part in it, or post a portfolio and resume.

Specialists in several areas are engaged in development. The industry is constantly evolving, new niches appear, and something becomes less in demand. But specializations that do not lose popularity, for example:

Web development.
Game development.
Gamemaking trends.
Mobile development.
Desktop application development.
Embedded systems programming

Web-developers are in the highest demand among programmers. The task is to develop a site, a page, a web application. There are three main specialties in the profession: Frontend-developer, Backend-developer and Fullstack-developer.

Game Development
The process of creating computer games (from development and design to release to the market) can involve one person or an entire organization. The developer creates games for personal computers as well as for mobile devices. It can also be an online game platform.

Mobile development
A mobile developer creates programs for smartphones, tablets and other devices on iOS and Android platforms. Here you have to be a designer, an analyst, and a backender to be able to tie the process together.
