Learning software and programming has become easy and accessible to the public in the last two decades thanks to the initiatives of several institutions and technology organizations that have launched online courses on their own or third-party platforms. In the online education deluge that has taken over the world in recent years, the largest share of learning has happened in the software development and programming sector. According to a 2023 report by Class Central, an online review and survey portal, programming courses continue to be the most popular option among the top 250 online courses in the world. The beauty of most of these courses is that even people from non-programming backgrounds can take up these courses and grow from beginners to masters within a span of a few months. So, here we are going to take a look at the best programming languages to learn in 2023 to give you a clearer idea of which programming language is most suited to your aspirations and which course best suits your requirements. Read on to know more.

Top Ten Must-Learn Programming Languages for Aspiring Developers in 2023

Below we have listed out the most popular programming languages that are creating waves in 2023.

1.    Javascript

Javascript is a high-level programming language that powers the internet. It is the most popular client-side programming language used in around 98% of the websites on the internet. Javascript is a relatively easy language to learn and implement, given you have a prior understanding of HTML and CSS. It is cross-platform as it operates on all types of device platforms (mobiles, PDs, and tablets). Moreover, it reduces the demand on the website server as it can handle several operations on the client side efficiently. The average annual salary of a Javascript programmer is estimated to be $112,152. So, learning Javascript introduces you to highly lucrative career opportunities.

2.    Python

Python is a highly readable and extremely popular programming language. Not surprisingly, it has continued to be the most popular programming language in the world for close to a decade. It is a free, open-source language with a gigantic community to avail support and inspiration from. Since it is a simple high-level language, Python is the most suitable language for beginners who wish to start their programming careers. All it requires to be a Python programmer is the ability to think in abstract terms and quickly solve problems. Python is a scripted (not compiled) language. The other great advantage of learning Python is the availability of a wide range and number of resources from highly reputed sources for you to learn from. Python programmers are projected to earn an annual salary of $109,092 as per the latest estimates.

3.    Go

Widely considered a ‘minimalist’ language, Go is an easy programming language to learn, particularly if you already know another programming language. Developed by Google, Go is mostly used in desktops, although it has cross-platform capabilities. The popularity of Go has seen massive increases in the last few years due to its simplicity, speed, and readability. However, since it is designed to resemble human language to a large extent, you might have to write more code for the same purpose compared to other syntax-based languages. Furthermore, Go is mostly used for developing Google applications. So, it has comparatively less library support and a smaller developer community as of now, although this is fast changing. ‘Go’ programmers represent a rare niche in the programming community and, as such, have a higher projected annual average salary of $141,654.

4.    Java

Even though it is an older and more complex programming language, Java is still used in more than 3 billion devices across the world and powers the backend of Goliathan websites like Google, Amazon, Twitter, and Youtube. It is still used in web application development and in new-age technologies like big data due to its portability across platforms and Write Once Run Anywhere (WORA) characteristics. However, learning Java takes time as it requires a basic mastery of object-oriented programming structures and has its own vast and unique vocabulary. Java is the first language taught to aspiring programmers in institutions and universities because it enables them to think like programmers and makes learning other programming languages easy.

5.    Kotlin

Kotlin, a language that was built to be better than Java, is extensively used for building Android apps, desktop applications, web applications, and server-side applications. It is a general-purpose programming language that is interoperable with Java and many other programming languages. Google applications are widely-built on Kotlin. However, learning Kotlin requires a basic mastery of Java or any other object-oriented programming language. However, once learned, it requires you to write much less code than Java. Kotlin developers are projected to earn $136,000 on average annually.

6.    PHP

This open-source programming language created in 1990 is on the back end of more than 89% of websites on the internet, including giants like Facebook and Yahoo. PHP is mostly used to write server-side scripts and command-line scripts. For someone with a prior background in programming, PHP is considerably easy to learn. Its cross-platform capabilities make it suitable for developing desktop, mobile, and web applications. It can be easily integrated with many tools and also with databases. However, being open-source comes with its own set of flaws. PHP can support only a limited number of apps at a time and is not too popular for its error-handling capabilities. Moreover, it is not highly secure and is comparatively more prone to cyber threats. PHP programmers will earn a projected average annual salary of $107,409 in 2023.

7.    C#

This open-source language, developed by Microsoft and used by one-third of all software developers, became popular as it supports the object-oriented programming framework. It is a cross-platform programming language best suited for Windows, Android, and iOS development and is scalable, updateable, and interoperable with other programming languages. It takes the support of the Integrated Development Environment (IDE) Microsoft Visual C++. Learning C# is easy if you have a basic understanding of how to write code. C# developers earn $111,760 on average annually.

8.    Swift

Swift programming language was developed by Apple Inc for making Linux, Apple iOS, and Mac applications. Developing applications using Swift requires almost no prior coding experience, just a willingness to read large manuals and tutorials that are freely available. It is not only easy to learn but is also faster, contains less code, and is open source. However, Swift has poor interoperability with other programming languages and third-party tools. A Swift developer, on average, takes home a salary of $109,652 annually.

9.    R

This open-source programming language, which is a variation of the ‘S’ programming language, is mainly used by Data Science professionals as it is built for processing statistics problems, linear and non-linear modeling, analysis, testing, and visualization. R applications are mainly desktop-based but are cross-functional with Linux, Windows, and Mac OS. The language, which is ideal for machine learning applications, boasts huge worldwide support for managing data and a plethora of libraries and packages. It has some security and speed constraints compared to other languages used by Machine-Learning engineers, such as Python and Matlab. Regardless, R is one of the most popular programming languages today, offering an annual average salary of $90,940.

10.                   Ruby

The programming language Ruby, developed in the 1990s, was primarily designed to be human-friendly and readable. Its simplicity has made it enormously popular in the last decade. Mainly used for developing web applications, Ruby is supported by a web development framework called Ruby on Rails (RoR) developed by the same team. Moreover, Ruby is flexible and known to enforce a good programming style among developers that is beneficial while using other languages as well. Ruby developers earn $121,070 on average per annum.
