Top 5 programming languages in 2020

Each programming language is good at something specific but not good for others. It is an essential thing for developers to know more than one programming language to choose the right tool.

Technology has been evolving and making our lives easier with several forms of implementation, it is important to choose the right language which is highly in demand.

Every year Stackoverflow publishes insights on developer surveys. Those insights cover lots of different aspects of the developers around the globe.

Programming language is not about learning loops, methods, variables, there is a lot of stuffs to do.

The list of top 5 programming languages compiled from the Stackoverflow annual developer survey as well as my own experience.

#5-GoLang

Go is a procedural programming language. It was developed in 2007 by Tech giant Google but launched in 2009 as an open-source programming language. Google’s versatility reflects in this language. It can be used from Machine Learning to Web Development but it is highly recommended for software development due to high scalability. It has some interesting frameworks like Revel, Beego, etc.,

It is going to produce a great amount of raise in 2020 — that’s my own prediction. It can handle large amounts of data and services. It is popular on the backend side. But in 2019 it did not get so much popular that the language deserves.

Why Golang?

1. Open source by nature.
2. Fast, Concurrent and Cross-platform
3. Has a garbage collector
4. Keeps the bugs away

It is worth checking Go in 2020.

#4-Swift

Swift is a powerful and intuitive programming language for macOS, iOS, watchOS, tvOS and beyond. Writing Swift code is interactive and fun, the syntax is concise yet expressive, and Swift includes modern features developers love.

We can see a small decline in Swift in 2020 because now we have a ton of resources to enter into the iOS market like ReactNative, Flutter, etc.,

Why Swift, not ReactNative/Flutter?

1. Better readability
2. Low maintenance
3. A better approach for error handling
4. Dynamic libraries linking support
5. Needs less coding
6. Speed

Though you can develop apps in both ReactNative and Swift, some of the complex features can only be done in Swift. It has very good potential and less competition there. So, it can be still worth to take a look at Swift in 2020.

#3-Java

Java is a popular programming language, created in 1995. It is owned by Oracle, and more than 3 billion devices run Java. It is used for Mobile applications (especially Android apps), Desktop applications, Web applications, Web servers and application servers, Games, and much, much more!

Java is not only the way to enter the android market, like the iOS market it also has a ton of resources to reach out. There is a little decline in the popularity of Java in 2019. Keeping Java still popular is Spring Boot. By the latest updates of Spring Boot, it has become fantastic.

Why Java on #3?

1. Widespread acceptance
2. Large community developers
3. Strong memory management
4. Backend Compatability
5. Top-notch security
6. High performance
7. Cross-platform

If you wanna learn Java in 2020, extend your knowledge up to Spring Boot.

#2-Javascript

Android or iOS or Web — Javascript is everywhere!

JavaScript is a feature-rich object-based scripting language, multi-paradigm, single-threaded, dynamic language, supporting object-oriented, imperative, and declarative (e.g. functional programming) styles. It is used both for front-end and back-end.

Why JS on #2?

It provides the ultimate business solution, that’s the reason why it is #1 in the local job market. No matter how greater you are building your project, no matter how much you apply Machine Learning or other stuff, people still need an interface, that can be in android or iOS or Desktop. JS provide all solution out there. It has a lot of frameworks starting from front-end to back-end like ReactJS, VueJS, AngularJS, NodeJS, etc.,

Github repositories-60,000+

If you have JavaScript on your resume, you have a lot of opening starting from tech giant Google.

#1-Python

Already all have predicted it, that’s none other than Python.

1. Python is a widely-used general-purpose, high-level programming language.
2. Python allows programming in Object-Oriented and Procedural paradigms.
3. Python programs generally are smaller than other programming languages like Java. Programmers have to type relatively less and indentation requirements of the language make them readable all the time.
4. Python language is being used by almost all tech-giant companies like — Google, Amazon, Facebook, Instagram, Dropbox, Uber… etc.
5. The biggest strength of the Python is large library which can be used for the following

• Machine Learning
• GUI Applications (like Kivy, Tkinter, PyQt,etc.,)
• Web frameworks like Django (used by YouTube, Instagram, Dropbox)
• Image processing (like OpenCV, Pillow)
• Web scraping (like Scrapy, BeautifulSoup, Selenium)
• Test frameworks
• Multimedia
• Scientific computing
• Text processing and many more!

It is worth learning Python in 2020.

Conclusion

There are several other languages that may also gain popularity in 2020 as seen on the survey chart. Your programming journey may not be an easy one but with practical knowledge of any of the five programming languages mentioned above, your career growth is certain in the year 2020.

Almost every next programmer that you see in the early days wants to become a data scientist or machine learning expert. There is a huge number of people looking for a job in those fields. There is another side of building interfaces. There will be a shortage of programmers in building interfaces in 2020. So, it is totally your choice to go to the crowd or stand away from the crowd.
