Most In-Demand Programming Languages In 2020

in demand programming languages

In this article, you will find out what these programming languages and their implementations are, so you can decide for yourself which programing language you should learn to increase your skillset for data science.

1. Python

Python is one of the most popular programming languages. Among people from all fields including software engineers, mathematicians,  data analysts, scientists, and more. It is a very beginner-friendly programing language, so people from different disciplines use python for a variety of different tasks. Such as data analysis and visualization, artificial intelligence and machine learning, automation. This is one of the biggest uses of Python amongst people who are not software developers. If you constantly have to do boring and repetitive tasks such as copying files and folders around, renaming them, uploading them to a server, you can easily write a python script to automate all that and save your time.

It is also great for people who constantly have to work with PDFs, CS view files, download websites and parse them; you can now do all of that automatically with Python. You don’t have to be a software developer to use Python; And you can be an accountant, a mathematician, a scientist or just about anyone who wishes to work efficiently. Python can also be used to build different kinds of web, mobile and desktop applications. It is also used in AI and machine learning, data analysis and hacking. It is a versatile and multipurpose language.

In python, you can solve complex problems in fewer lines and less complex code. Which is a big plus and gives it an edge over other programming languages. Python stands on the second position of most loved language, after Java, in Stack Overflow Developer as per the survey results for 2019.

Another reason why Python is so popular is that it is a high-level language that can deal with complex tasks, its cross-platform features allow apps to run on Mac, Windows, and Linux. It has a huge community so whenever you get stuck you can easily get help and the large ecosystem means that whatever you are doing someone has already done on Python, which is a great help too.

2. Java

Java is one of the most fundamental languages that produces software for multiple platforms, and the best thing is that it is machine independent i.e. it can be written once and run anywhere. It is a fast, secure and reliable general-purpose programing language. Java and Python have been the two most popular languages of the decade. It ranked number one in Stack Overflow Developer Survey results for 2019.

Java is faster than Python because it is statically typed, but its legacy is more of a coding style making it larger and more numerous. It has multiple uses, it is used to build android apps, and website applications, for example, Google Docs. Companies like eBay, Uber, and Airbnb also use Java for at least a part of their websites and web applications.  It is also used in games, car navigation systems and medical devices from prosthetic limbs to glucose monitoring devices.

Java is the one behind ATMs and industrial robots. Java also controls most of the smart devices that are used in homes today – from light bulbs to garage openers you’ll find that Java-powered logos. There is even an entire line of home appliances that are connected to the internet and leverage the Java programming language. Java makes it easier to learn other programming languages. If you know Java you are more likely to pick-up easily on other computer programming languages.

Java is the big player in the Internet of Things (IoT) and connected device market. Java is a mature language and many tools used to build Java applications are incredible! These tools are called Integrated Development Environments (IDE). They provide information about code refactoring, errors, and reformatting, making Java development experience much easier.

3. JavaScript

JavaScript is a programming language that runs in your browser, which is one of its unique features. In other words, it is the only programming language that can be understood by the web browser. Other programming languages like Ruby, Python, C, Java all need to be on a server, and that server has to build up all the processes and wrap that code up in a way that the browser can interpret it. You can write code in javascript in the browser and the browser can interpret the code and then run the program.

Some of the world’s powerful applications are built-in JavaScript. Gmail, Facebook, Twitter use JavaScript extensively. In fact, Google and Facebook have come up with their JavaScript framework.  If you are willing to become a developer, this is a great language to learn, especially if you want to make mobile applications then JavaScript is a great language for you to learn.

In the early stages of mobile app development, you had to learn very challenging languages, for example, if you wanted to build an app for the iPhone, you would need to learn Objective C language. Similarly, if you want to make some apps for Android, then you would have to build in the Java programming language. Over the time JavaScript developers took their libraries and built out these frameworks that allow you to build your application using nothing but JavaScript that ties in directly to your smartphone API. This means using JavaScript you can build an application that can use a camera, location or accelerometer. JavaScript is also one of the most powerful tools you can have to automate your day-to-day workflow.

4. C/C++

C++ is not one of the most popular languages, usually, the popular chart is taken up by languages like JavaScript or Python or Java or Swift. Even though it is not popular, it still is one of the most powerful and underlying languages. Most of the frameworks that you workaround or interact with are somehow linked by C++, for example, Flutter, a famous platform that is getting increasingly popular.

C++ isn’t a language for beginners. However, you could learn it if you want to expand your portfolio and get better jobs. It is usually preferred for game development.

C++ is really powerful and can do a lot of things, it is faster than Python and does not have any dependencies on the interpreter. C++ is completely capable of interacting with modern web applications. This language comes up from the academic side and people who are doing masters or Ph.D. usually get in touch with this language, but it is in demand by most tech companies.

5. Ruby

What do you think of scripting languages? Unlike Java, which is an object-oriented programing language, Ruby is an object-oriented scripting language, which makes it suitable for coding, writing, etc. It was designed by a Japanese man named Yukihiro Matsumoto. It was sort of regarded as pr2 Python. In fact, both scripting languages even came around at the same time and used for web programming like writing servers and back-end web services. So the two big frameworks that were competing were: Ruby Rails, the foundation of Twitter and Python Django. However, Python ended up overtaking Ruby.

The back-end scripting war kind of stopped once Nodejs came out and now apparently you can write front-end code in Ruby and Python-like most languages. Ruby has its dedicated package manager, it is called Gem and if you head to rubygems.org you can view all the types of different packages people write for Ruby. It is basically like NPM for Nodejs. Ruby is a bit unique because Matsumoto wanted to make a language that made programmers happy to write codes on and it’s crazy that he was able to pull that off with an object-oriented programming language. So in Ruby, everything is an object even like primitive numbers will have a class type essentially and you can call functions on them.

These were the top five languages in demand. Following are the emerging programming languages of 2020 that are also in great demand by big companies, in no particular order:

6. ELIXIR

Elixir first came out in 2011. It is inspired by the Ruby ecosystem, it is a dynamic and functional general-purpose programming language. Elixir runs on the Erlang virtual machine and is used for developing scalable applications that can be easy to maintain.

With a moderate coding style, Elixir permits a client to note down codes in a short and succinct manner. It used to create high-availability, low-latency systems. Elixir is also utilized for web development. If you learn Elixir, it can get you well-paid jobs.

7. KOTLIN

Kotlin has an edge since it is the programming language for Android, cross-platform and web advancement. The language is proficient in decreasing standard code and plays safe by confining null-pointers special cases. A client can use any library on JVM because of a 100 percent similarity alongside SAM support. According to the annual JVM report 2020, Kotlin has acquired the second position, ahead of Clojure and Scala.

The main supporters of Kotlin are Netflix, Uber, Foursquare, Google, Amazon, and many others. A lot of times when people face problems with a certain app, it’s not because of the poor functionality of the app, it is sometimes because of poor internet connection. Windstream Customer Service fixes all your internet related problems immediately enabling you to work efficiently.

8. RUST

Rust is sponsored by Mozilla Research and is very similar to C++. It takes best practices inspiration from modern C++ such as RAII and smart pointers. There are many C like languages that result in memory errors when doing manual memory management, but Rust handles it very efficiently.

Rust’s analysis tool makes it possible to stop code if it could cause a potential memory error. Whoever has worked on C/C++ knows how much trouble it is when it comes to installing dependencies and compiling code on multiple platforms. Rust makes it easier by providing a sane package manager and cross-platform compatible APIs. Rust manages memory at compile-time and static dispatch for generics, which is similar to C++ templates and more type-safe. That’s the reason that RUST is one of the most in-demand programming languages.

9. SCALA

Scala was designed back in 2004. It is an open-source language and is a perfect combination of object-oriented and functional coding in a statically-typed programming environment. With the downfall of Java, a lot of programming languages have emerged. Scala, Clojure, and Kotlin have especially gotten a lot of traction.

Scala was designed to fill-in for the flaws of Java in terms of general-purpose and hence can be the ideal replacement of Java. It stood 4th on the Annual JVM report 2020.  Scala is also particularly in demand because of its concise coding. Compared to Java, Scala requires less number of coding lines to perform similar tasks. It is a highly scalable, typed-safe language with enhanced quality and multi-platform presence. There are just a few issues with Scala that it is a little difficult to understand, it has slow compilation speed and some issues with binary compilation. Even then, it is one of the most in-demand languages these days because of obvious reasons. It is appreciated by LinkedIn, Tumblr, Apple, Airbnb, and many others.

10. CLOJURE

Clojure is also a dynamic general-purpose programming language and is ranked 3rd on the annual JVM report 2020. Even though it compiles directly into JVM bytecode, it still remains dynamic. A lot of developers prefer Clojure because it is a dialect of Lisp, it has a concise syntax, has persistent data structures and concurrency. Companies like Soundcloud, CircleCI, Nubank, Groupon, etc use Clojure. Hence it is in demand and can give you an edge over others if you know this language.
