5. Go – GoLang
Go is an open-source programming language designed by Google in 2007. Its often referred to as Golang because of its domain name (golang.org). The syntax for Go is similar to C but it also features memory safety, garbage collection, structural typing, and CSP-style concurrency.
According to the latest Stack Overflow Developers survey, Go is among the five most popular programming languages. Currently, many big companies including Google, Uber, and DropBox are using Go. If you’re opting to learn Go, then here’s an extra perk, the developers of Go, Perl, and Scala have the highest salaries.
Developed by Mozilla Corporation, Rust has been the most loved programming language for the fifth year in a row. 86.1 percent of Rust developers don’t just love the language, but also want to continue working on it.
Initially, Rust was intended to be used for low-level systems programmings like C and C++. But, what Rust adds to the mix is performance and safety. It ensures memory safety without garbage collections.
Overall, Rust is intended to be used for highly concurrent and safe systems. Big companies like Coursera and DropBox are already using it internally. It’s not really one of the programming languages to learn first, but as you can see from the Stack Overflow survey results, once developers get the hang of it, it becomes their favorite!
If Swift is the language of choice for iOS developers, then Kotlin is the popular choice among Android developers. In the Stack Overflow survey, Kotlin was ranked the fourth most popular programming language. It was also declared the preferred language for Android app development by Google ad there’s a growing number of Kotlin users on the GitHub Community.
Kotlin is a statically-typed, cross-platform, general-purpose programming language. It supports both functional and object-oriented programming features. It is mainly popular for Android development, but can also be used for web development and desktop app development.
What makes Kotlin unique is nothing unique. In fact, the language draws inspiration from other programming languages, which makes it easy to learn and use. For Java developers, Kotlin is straightforward because it’s completely interoperable with Java. It even supports all Java libraries.
Big companies like Netflix and Uber are offering some exciting career opportunities to Kotlin developers. Currently, the salary of a Kotlin developer is about $99k.
Following the lead of Kotlin, Scala was also developed to overcome the issues faced in Java. it’s a powerful, statically typed, general-purpose programming language. It supports both functional and object-oriented programming.
This programming language is similar to Kotlin, which is interoperable with Java. It means that the libraries in either language can be referenced directly into the other. You can also compile the Scala code to Java Bytecode and run it on a JVM (Java Virtual Machine).
Scala also supports a curly-brace syntax similar to C language and Java. Scala can be used for the same systems like Java, but it’s used mainly for big data processing and machine learning.
Several tech giants including Netflix, Twitter, LinkedIn, and eBay are using Scala for their respective platforms. The average salary of a Scala developer is $117k per year.
Currently, TypeScript is growing in popularity and is among the top ten most popular technologies. It’s also the second most popular programming language of developers surpassing Python from last year.
Java is a concurrent, class-based, object-oriented programming language that sees widespread use. It is regarded as the easiest programming language to learn and get a working knowledge of how classes and objects work.
It sees extensive use in many different areas ranging from web development to games to even scientific and financial applications. If you’ve used any electronic device, chances are, you have used something made on Java. One of the most well-known mobile operating systems – Android – uses apps made with this language.
There is a lot of competition here; it doesn’t offer an easy place for one to establish themselves as major players without significant experience and knowledge.
Your best bet is to start with a course covering the basics before trying to teach yourself more advanced aspects of this coding language.

11. Ruby on Rails
Ruby on Rails is a model-view-controller (MVC) framework. It abstracts and simplifies common repetitive tasks, making it easier to build websites and applications.
It primarily sees use in web development and has been growing in popularity steadily. Given its efficiency and simplicity, it has been firmly establishing itself as a major tool in the market.
The job market for Ruby on Rails may not be as vast as that of other best programming languages but it is a relatively new technology compared to languages like HTML and Java. Ruby on Rails is on track to establish itself as an industry standard and the job market should continue to reflect that.
It is a fairly straightforward programming language to learn and as an open-source one, it has oodles of documentation detailing its use. Several online courses should give you a jumpstart on this coding language. However, like all other skills, practice makes perfect, which holds true here as well.
HTML is a markup language, while CSS is a style sheet used to build the design for a markup language. The two are relatively straightforward and go hand in hand more often than not.
HTML/CSS is used almost exclusively to build websites. Everything from what shows up on your web browser to point links in the right direction requires an understanding of HTML.
Given the constant requirement in the market for not only new websites but also website maintenance and updates, the job pool for HTML/CSS is vast and has something for coders at any skill level.
It is one of the most future-proof skills as the demand for ‘taking businesses online’ will only grow over the next decade. Best way to learn HTML is by practicing. Follow a few web design courses or tutorials and build a few basic websites and you’ll soon find yourself improving dramatically.
PHP is a general-purpose scripting language that runs on the server-side, i.e. it runs on code that is executed on the web server – giving the user no way of accessing the actual code (unlike HTML).
PHP sees a lot of use in web development. In fact, entire websites can be enclosed in PHP, rendering it virtually impossible for anyone to reuse your code. It can also be used for executing scripts for simple text processing tasks.
PHP on its own has a rather limited job pool. When coupled with other popular programming languages, HTML in particular, opens up a plethora of job opportunities. There are jobs suitable for those with a basic understanding as well as advanced users.
14. SQL – Structured Query Language
The backbone of many websites, SQL is not strictly a programming language; it is called a ‘query language.’ In conjunction with PHP and HTML, SQL is a language that allows you to query large databases.
Although the use of ‘No SQL’ databases like MongoDB has negatively impacted its use, many old web applications and websites that do not see any reason to switch – continue to run using SQL.
However, this stiff competition makes the future-proof aspect of SQL doubtful. Nonetheless, it is a useful and still popular programming language that teaches you the basics of schema-based databases and their work. As of now, there is still a demand for back-end developers proficient in SQL.
SQL itself is relatively easy to learn for a beginner, the nuances of databases do confound people new to the concept. Enrolling in an online course is enough for you to become proficient in this language.
C++ is an extension of the language C and is one of the most used and popular programming languages with a wide variety of applications. It is a high-end language with imperative, object-oriented, and generic programming features.
Although it has primarily seen use in the development of desktop applications, it has also served as the inspiration for several other programming languages that see widespread use in this day and age. Interestingly, advanced games and game engines that millions play require the use of C++. In fact, Apple’s preferred Objective-C language (used to make apps before the release of SWIFT) was another extension of C (the language).
Though it may not be as widespread as it once was, it still has a healthy job market, though it is skewed towards more experienced programmers. However, it is still a great skill to have, especially as mastering the language guarantees a fat pay package.
C++ is a classic example of ‘easy to learn, hard to master.’ Hence, Java is still preferred as the go-to coding language for beginners wanting experience in object-oriented programming languages, before moving onto C++.
