Outstanding Devs: Top Programming Languages to Learn in 2020

One of the most important skills for today is the ability to write a program. After all, computer technology is everywhere, from factories and transport to home appliances. They have greatly simplified our lives. An ordinary user, as a rule, heard about 3-4 programming languages. But professional coders know that they are many times more. According to various sources, on average today there are between 500 and 5000 programming languages. These top popular programming languages help you to get a new software developer job in 2020!

Most Popular Programming Languages to Learn in 2020 are:

1. Kotlin
2. HashiCorp Configuration Language: HCL
3. Go
4. Javascript
5. Typescript
6. Python
7. Java
8. PHP

But among them, year after year, programmers trust only a dozen (if not less).

Trends, Ranking and Statistics

Obviously, a language chosen for subjective reasons. But for me, it was a surprise to see a huge difference in polls from different sources. This article was prepared by team of software developers, project managers, and business developers to understand what is going to be popular in the coming year and what you shall learn if you didn't do it earlier.

Github Data

One of the largest IT hosts annually publishes statistics on the use and development of programming languages, frameworks and libraries. Their audience includes about 31 million developers and at least 2 million organizations. Therefore, the indicators can be considered quite reliable.

As can be seen, the same languages fall into the top 10 of the last 5 years (with the exception of TypeScript, which broke into 7th place only this year). Remarkably, the top four is completely unchanged. It is clear that the programmers have not yet discovered anything new and prefer proven options.

They also published data on the popularity of languages in different parts of the world:

Javascript and its frameworks are consistently the best, regardless of region. Speaking about the sensation of the year - TypeScript, it is worth noting that it is mainly used in South America and Africa. Presumably, this is due to the younger community of developers of these regions, which are aimed at new technologies. And TypeScript in this regard is considered one of the newest.

PYPL-index and Tiobe

PYPL and TIOBE are two indices that analyze the popularity of programming languages according to the frequency of search queries. PYPL explores Google trends exclusively, while Tiobe takes data from Youtube, Wikipedia, Bing and other popular systems.

But there is one nuance: PYPL examines only the pages that describe the programming process, and TIOBE creates a rating based on all sites where there is at least a mention of a language. Because it is less accurate. I provide the latest published data so that you can be sure.

The data is significantly different from Github ratings. First of all, Javascript takes only third place, behind Java and Python. Typescript in this list is located on the 11th place, Ruby - on 12. Well, such programming languages as Shell and C did not even make it to the Top-20.

I will go to the TIOBE statistics:

The first thing that catches your eye is seventh place for Javascript and 8 for PHP. In general, the figures are significantly different. Personally, it's hard enough for me to believe that these two languages have such low popularity. Because every SEO optimized website created thanks to it.

Stackoverflow

You could say that I unreasonably withheld. But I want to provide the results of a survey of programmers conducted by Stackoverflow, drawing attention to some of the details.

First of all I draw attention to the fact that immediately after Javascript, the tip is occupied by 3 languages that I have not mentioned before: HTML, CSS, SQL. A survey of professional web developers showed the same ratings, with only a small percentage difference.

Typescript and Ruby in this ranking took 12 and 13 places respectively. But Visual Basic. NET is located at 18, while TIOBE is 6 at index.

Much more interesting statistics - the most loved, dreaded and wanted languages. VB.NET ranked the top 4 in the second category. Typescript after the 4th place in the first and third categories. Also high positive results in the most popular languages - Python and Javascript.

What to look for

Having studied all the statistics, we can distinguish several programming languages that will definitely be a trend in 2020.

Front-end

Javascript

Javascript is the front-end programming language most widely used in the world for developing web applications like SPA or MPA. It allows you to create all the animations, set up a lot of buttons, manage multimedia and much more. In other words, Javascript is the unconditional basis for front-end development and its frameworks Angular, React and Vuew .

Javascript benefits in 2020 are:

• high speed due to the ability to run through the browser on the client side;
• easy to learn;
• it is perfectly combined with other languages;
• the ability to create a crowded interface;
• annual updates.

Javascript Disadvantages in 2020 are:

• since the code is executed on the client side, this somewhat reduces the security of the user's computer;
• scripts can be executed differently depending on the browser.

A unique feature of Javascript is a set of functional frameworks. So, Node.js with Express.js allows you to use this programming language to run server-side scripts.

80% of companies require candidates for work knowledge of Javascript and the presence of experience in its environment. That’s why this language is a constant trend for several years.

Typescript

As the popularity of Javascript grows and its use by large companies, the process of simplifying the writing of code and its maintenance becomes more and more difficult. For this reason, Microsoft developed Typescript, which extends the capabilities of JS. In addition, applications written in Typescript can be compiled into Javascript.

Typescript Benefits in 2020 are:

• a complete description of each component of the code, which eliminates the likelihood of a violation of one element when changing another;
• requires fewer tests due to the special architecture;
• extended toolbox;
• the ability to configure so that the erroneous code did not commited.

Typescript Disadvantages in 2020 are:

• to integrate the libraries, it is necessary to describe each module in order to avoid compilation errors;
• few professionals;
• the code is written longer than in JS.

As the statistics of Github and PYPL showed, this language is gaining momentum, and its community is expanding. The documentation is very well designed because it is not so difficult to learn. Despite the shortcomings, it is highly likely that its ratings will increase significantly by 2020.

HTML 5

HTML allows you to organize all the page content. It is also widely used for web page layout and is considered fairly simple to learn. Very often they start their programming path with HTML.

HTML 5 Benefits in 2020 are:

• easy to create sites;
• supported by any browser;
• optimizes the appearance of the page for any device well;
• lightweight files;
• completely free.

HTML 5 Disadvantages in 2020 are:

• impossibility of correct interpretation without a browser;
• creates only static pages;
• you need to write large code to create simple pages;
• low security level;
• each page must be created separately.

It cannot be said that this language will be used by large corporations. Its functionality today is not enough to create sites of the 2020 level. Nevertheless, it is still good for beginners and will often be used to create news portals, online stores and more.

Back-end

Python

One of the most popular server-side programming languages. According to the latest PYPL statistics, users most often seek training and assistance in working with Python. As a rule, it is used to write scripts and plug-ins. For example, through Python are recorded episodes and actions of characters in games.

It is a universal language with easy to read code. Due to the features of the syntax, programmers need to perform fewer actions to create a plugin than in Java or C ++. Brands like Instagram and Surveymonkey use it. Google, Netflix and Quora cannot do without Python.

Python Benefits in 2020 are:

• very simple code;
• the possibility of asynchronous coding (alternating the execution of processing cycles);
• supports most libraries;
• free;
• open source;
• object oriented.

Python Disadvantages in 2020 are:

• despite the simplified way of writing code, many processes run long enough;
• weak for mobile application programming;
• requires many tests to completely eliminate errors.

Many advice Python to absolute programming weasels for initial learning. Ideally, after 2-3 lessons, you can write a simple code.

Python ratings are growing noticeably. In the past, statistics put it in 4-5 places, but in February 2019 it was already in the first place in the number of search queries. More detailed statistics will be only at the end of the year. But now we can confidently say that this is the main trend among programming languages.

Java

Another popular choice of programmers. This language is widely used by large enterprises to create applications of various kinds. The Java environment is incredibly stable, making it the choice for writing Android applications.

A lot of sites today do not function without Java. It is noteworthy that every year there are more such services. Because of the demand for professionals who are well versed in this programming language, more and more.

Java Benefits in 2020 are:

• object-oriented programming;
• readable and easily manageable language;
• does not require a specific hardware infrastructure;
• good level of security;
• stability;
• automatic memory management.

Java Disadvantages in 2020 are:

• non-standard interface, which you need to get used to for a long time;
• consumes a lot of memory and reduces hardware performance;
• difficult to learn;
• limited critical delay setting;
• does not support general programming, which increases the amount of work when writing code;
• no possibility to make backup;
• slow.

What can I say about Java? Strong old fellow, to whom no one has found a replacement. It is a little behind the current pace of technology development. But thanks to the high-quality code compilation and high stability, it still occupies high positions. Recently, there has been a decline in interest in Java, but it is still one of the most desirable languages among programmers.

PHP

Despite the fact that this PHP is losing the battle of Python and Javascript, it is still highly ranked in the market. Today, about 70% of sites use PHP, and in Wordpress about 90% of the code is written using this language. Thanks to PHP, you can create very dynamic and interactive sites, which is very pleasing to the eye of the current user.

PHP Benefits in 2020 are:

• low knowledge threshold to get started;
• large ecosystem;
• huge community;
• high-grade debugging.

PHP Disadvantages in 2020 are:

• interpreted language: requires more resources and slows down code execution;
• multi-threaded execution (requires a lot of memory, but it is always limited);
• requires changing the configuration file to install extensions.

PHP is one of the most controversial trends. If you are up to date, most developers have called it the worst programming language. Moreover, due to the low threshold of knowledge, it is easy to stumble upon an amateur, rather than a qualified specialist.

Nevertheless, already over the years it occupies the top lines and, believe me, in 2020 it will be one of the most popular in the market.

Future trends

Finally, I want to draw a little of your attention to the little-known, but rapidly developing programming languages. They have great prospects to enter the top 10. Among them are Kotlin, HCL and Go. We have already begun compiling a list of the top programming languages ​​in 2021. The article is updated every month.

So far they have not gained much popularity due to the relative novelty and traditional approach of companies to developing applications. However, the appearance in the TypeScript top indicates that interest in new methods is growing. Therefore, watch out for these languages and study their features at your leisure.
