Top 8 Programming Languages You Need To Learn In 2021
As per Moore’s law, the computer processing speed doubles every 18 months. This increasing sophistication in computers has been facilitated by the introduction, and in some cases, the constant evolution of programming languages. To boil it down to finer details, it’s the code that instructs a machine of executing an action.
If you’re trying to advance in your career or change careers completely, and you realize you need to master a programming language, you might wonder which one to learn. After all, it will take time and money to learn the programming language, so you want to make the right choice from the start.
Whether you want to develop a mobile application, get a certification for programming knowledge, or learn new skills, you need to choose the right programming language to learn.
Top 8 Programming Languages You need to Learn in 2021
1. Python
Python was created in 1991 by Guido Van Rossum. It was introduced keeping simplicity and beautification in mind and is one of the best programming languages to learn in 2021 for top coders as well as engineering generalists.
It is used for scientific and computational applications like FreeCAD and Abacus, and it is also by popular websites like YouTube, Quora, Pinterest, and Instagram.
Key features are:
- Open-source programming language
- Extensive support modules and community development
- Easy integration with web services
- User-friendly data structures
- GUI-based desktop applications
Mainly Used in:
- Data Science
- Data Analytics
- Artificial Intelligence, Deep Learning
- Enterprise Application
- Web Development
2. JavaScript
JavaScript is an object-oriented computer programming language commonly used to create interactive effects inside web browsers.
Alongside HTML and CSS, JavaScript is one of the three core technologies of the World Wide Web. It is also used at the front end of several popular websites like Google, Wikipedia, YouTube, Facebook, and Amazon.
Featuring asynchronous event handling and crisp syntax, it has found widespread use in the field of web development. What started off as a simple client-side scripting language, is now a highlight within the web development community featuring multiple frameworks for both backend and frontend development.
Key Features are:
- JavaScript is the undisputed king in Browser programming.
- Thanks to Node.js, JavaScript offers event-driven programming, which is especially suitable for I/O heavy tasks.
- JavaScript has gone through massive modernization and overhaul in the last several years, especially in 2015, 2016, and later.
Mainly Used in:
- Web Development
- Backend Development
- Mobile App Development
- Serverless Computing
- Browser Game Development
3. Java
Java is one of the most common, in-demand computer programming languages in use today.
Well, think of some of your favorite web apps and games. It’s highly likely that Java plays a huge role in the code that makes them work. Another important factor which has kept Java’s magic intact among web development companies is its independence from platforms.
In recent years, Java has lost some of its markets to highly developer-friendly modern languages and the rise of other languages, especially Python, JavaScript.
Key Features are:
- Java offers a powerful, feature-rich, multi-paradigm, interpreted programming language with a moderate learning curve and high developer productivity.
- Java is strictly backward compatible, which is a crucial requirement for business applications.
- Java’s runtime JVM is a masterpiece of Software Engineering and one of the best virtual machines in the industry.
Mainly Used in:
- Enterprise Application Development
- Android App Development
- Big Data
- Web Development
4. Go
Developed by the tech giant Google itself, Go is one of the latest players in the programming platform. It is an open-source language which makes it easy to create simple, secure, and productive software.
Development efforts behind creating Go wanted to retain useful characteristics such as static typing, runtime efficiency, networking, multiprocessing, and readability/usability of code.
Although Go is a bit feature anemic, it has become a mainstream programming language in a short period.
Key Features are:
- Go has language-level support for Concurrency. It offers a CSP based message-passing concurrency via Goroutine (lightweight Green thread) and Channel.
- The biggest USP of Go is its language design and simplicity. It has successfully combined the simplicity and productivity of Python and the power of C.
- Go has embedded Garbage Collector (albeit not as mature as JVM garbage collector). Go developers can write system programming with the safety of Java, Python.
Mainly Used in:
- System Programming
- Serverless Computing
- Business Applications
- Cloud-Native Development
- IoT
