The IT world does not stand still. New languages appear, replacing the old ones. Today we will tell you about those languages that are getting lower and lower in the overall rating every day. They are no longer in high demand, and it’s not worth studying now.
The article is written based on data from the PYPL rating (the popularity index of programming languages) and the Google Trends tool.
In the 2000s, Perl was one of the leading web programming languages: practical and convenient, but with its complexities. However, after the development of more modern programming languages, mostly Python, it became difficult to stand out in the market.
Today Perl includes two versions: Perl 5 and Perl 6 (or Raku). It is used for web development and GUI development. But Perl's popularity has decreased year after year. Therefore, it is better to tackle a more popular language.
Some people think that Haskell is essential for science and industry. Also, large companies such as Facebook, GitHub, IBM, and so on often turned to it because of its speed and reliability. However, in recent years, the popularity of this language has decreased.
So despite a significant upgrade to Haskell in 2020, it's not worth learning, especially at the beginning of your career.
The leader among programming languages in 2004 is losing ground, and its rating is gradually falling. Now it ranks 18th in the PYPL rating, and according to a StackOverflow survey, Visual Basic has proven to be the most unpopular, even surpassing Objective-C.
This language appeared in 1991, and to this day, it finds an enthusiastic response in some people’s hearts. The reason for this is a straightforward syntax, which anyone who is at least a little familiar with English will be able to master. And it seems so tempting to not declare variables at the beginning of the code.
But such an approach seems exceptionally frivolous. In this language, there is no mechanism for inheriting the implementation of objects and pointers. It can only be used in Windows. And even so, it consumes a lot of resources. As a result, the code, the code may seem simple however it's still cumbersome, slow, and clueless.
Visual Basic finally lost to the C # language. In 2020, Microsoft announced that they "have no plans to develop Visual Basic." However, support on the .NET 5.0 platform will remain for now.
Elm is a functional programming language for front-end development. It appeared in 2012, and its popularity grew until 2018. But it fell over the next two years.
The problem is in rare updates. Elm looks outdated and "dead", especially for beginners who do not see much growth and development of the language. Besides, the market demand for Elm developers is lower than the supply. And programmers face serious competition.
As of 2021, CoffeeScript is dead to the market (although the GitHub repository is still partly alive). Knowledge of this language is not in demand and is an exotic (and not at all mandatory) addition to the basic skills.
The next programming language that is not worth learning is Erlang. Many organizations still use it. But modern companies prefer alternatives like Elixir, as they are more modern and accessible for beginners. Therefore, year after year, the demand for this programming language is falling.
Vacancies for Erlang developers still exist on the market. But if you want to stay competitive, you should choose a more popular and new language.
Of course, there are still many languages that are also losing their popularity. Studying them sometimes is just a waste of time. While using them, you lose the opportunity to discover many features of writing elegant and, most importantly, functional code.
