Top 7 programming languages ​​2021

Over the past decade, many programming languages ​​have come out. However, not all of them have taken root equally well in the software development world. And some, not surprisingly, were quickly forgotten. So, on the eve of the new year, I want to know what is better to study, and where to dig. This top 7 programming languages ​​2021 should not be considered as the ultimate truth. It is the quintessence of various ratings, survey results and personal experiences. Well, let’s get started.

Advanced Topics in Types and Programming Languages (The MIT Press)

The study of type systems for programming languages now touches many areas of computer science, from language design and implementation to software engineering, network security, databases, and analysis of concurrent and distributed systems. This book offers accessible introductions to key ideas in the field, with contributions by experts on each topic.

Which programming language do you consider the most promising in 2020?

1. Java

Despite having younger and more ambitious co-workers, Java still holds its ground. Besides the fact that you can write anything in it, it is one of the highest paid programming languages. If you wish, you can create a desktop application, a game, and a mobile application in Java. According to the ratingTIOBE in November 2019 Java held the first positions.

TIOBE rating

Buns:

  • cross-platform;
  • many frameworks for every taste and color;
  • relative ease of learning.

Minuses:

  • not very productive, despite all the tricks of the JIT compiler;
  • frameworks are quite cumbersome and complex.

2. JavaScript

It is extremely difficult to imagine a web application or site without JavaScript. It is by far the most popular language in the Stack Overflow developer survey.

Stack Overflow Developer Survey

Buns:

  • huge community, many tutorials;
  • can be run on any computer, there would be a browser;
  • is also quite easy to learn.

Minuses:

  • it is extremely easy to make a mistake due to the lack of compilation and type checking;
  • the code can be obfuscated, but not hidden.

3. Python

A programming language that continues to gain momentum. In the serpentine language, you can write whatever your soul desires. As a bonus, it is completely free and has a lot of libraries. Also today, Python is often taught in educational institutions. And, like the icing on the cake, neural networks, AI, robotics – Python has libraries for it all. The only thing that is extremely unusual at first is the syntax and complete indifference to everyone’s favorite semicolon.

Buns:

  • high processing speed;
  • many libraries;
  • availability on virtually any OS.

Minuses:

  • lack of access modifiers familiar in OOP;
  • unusual syntax.

4. C ++

The pros are still the base that serves aspiring programmers. Yes, shooting yourself a couple of toes or a whole leg in C ++ is as easy as shelling pears. However, it is really a very powerful programming language that allows you to create any software product. Plus, if you really know the language well, you have every chance of finding yourself on Google or Facebook.

Buns:

  • large community;
  • the ability to create productive and fault-tolerant applications;
  • iron compatibility.

Minuses:

  • colossal ease in shooting off limbs (difficult to learn);
  • many complex syntactic constructions.

5. C #

It is still a fairly young language that continues to grow the community. In essence, it is built on C and C ++, but more lenient towards developers. You can also write virtually anything on it. And more recently, cross-platform applications. The syntax is somewhat similar to Java, therefore, knowing one of these languages, you can learn the second relatively painlessly.

Buns:

  • ease of learning;
  • wide community and a bunch of online courses;
  • cross-platform.

Minuses:

  • too much syntactic sugar spawns a lot of shitty coders;
  • it is quite simple to disassemble, that is, your application can be easily disassembled into parts and hijacked.

6. PHP

Of course, there are a lot of jokes about PHP developers. However, the number of sites written using PHP is still large. The language itself continues to evolve and does not lose popularity.

Buns:

  • there is a legend that it is easy to study;
  • a large enough community;
  • lots of teaching materials.

Minuses:

  • the language is extremely narrowly focused;
  • some peculiarities when converting types, format 333 == ‘333foo’. (And don’t say it’s okay!)

7. Swift

Another young language. If you want to develop apps for Apple, Swift is just what you need. It is a fairly functional and practical language.

Buns:

  • ease of support;
  • careful use of memory.

Minuses:

  • the narrow profile is the main focus for Apple.

A few words about the choice

Actually, this is where our top languages ​​for 2020 ends. In principle, these languages ​​will enjoy the greatest popularity for more than one year. However, when choosing, I still advise you to focus on your taste or the taste of the organization, where you would like to go. But that’s a slightly different story. Most importantly, do not forget that language is primarily a tool. And don’t try to change the light bulb with a hammer.
