Top 10 in-demand programming languages

in demand programming languages




Trying to figure out what today’s most in-demand programming languages are is no easy task. With the tech industry expanding at an unprecedented rate, it seems like trends in programming languages change as much as trends on the high-street. Today, there are over 600 programming languages in existence, each with their own set of unique characteristics.


This makes trying to decide which programming language you should be writing in very difficult. To try and simplify things, we have compiled a list of the ten most in-demand programming languages for 2019. The list is based on Venturi’s 2018 placement data and reports from other leading websites such as StackOverflow and TIOBE.


Java is a general purpose programming language and can be run on many platforms such as Windows, Mac, Linux etc. This is thanks to its Write Once, Run Anywhere (WORA) feature. Java is ubiquitous within the tech world and is currently run on over 3 billion devices worldwide. It’s popularity with larger corporate organisations is one of the reasons it it is always an in-demand programming language. Another sign of its popularity is that in 2017 it was the programming language with the most job listings on Indeed.


Python is one of the most popular programming languages in use today. It is particularly popular amongst university undergraduates as it is considered relatively easy to learn thanks to its intuitive syntax. Some of the languages main applications include machine learning and AI. As these two applications are being increasingly integrated into data analytics, our placement reports show the demand for this language is growing larger by the day. According to the TIOBE Programming Community Index it has ranked in the top ten most popular programming languages every year since 2003.


C++ is an extension of the C language, one of the oldest programming languages in use. One of the reasons it’s so popular is because it’s extremely versatile. Many different software programmes are written in C++ from a diverse range of industries including: banking, gaming and retail. In 2017, it was the third most popular programming language in the world.  As it has been in use for so long, it is the language of choice for many software developers. Therefore, many job openings require all candidates have a basic knowledge of C++.   


A programming language that is predicted to grow in popularity in the coming years is R. R is a language used for graphics and statistical computing. It has many different applications such as data mining and data analytics. The language has shown a dramatic increase in popularity especially within bioinformatics. A field that is increasing in importance within the tech industry is data visualisation, a task which R is optimised for. These are just a few of the reasons why R is currently one of the most in-demand programming languages.


PHP is one of the most popular programming languages for web design. In fact, 80% of the world’s most popular websites are written in PHP (the page you’re reading right now is also written in PHP). In today’s digital age, a well designed, easy to use web page can be make or break for a company. This is why so many companies employ teams of people to continually update and improve their website to keep customers satisfied. Thus, understanding PHP is almost essential for a career in web design.


Swift is another popular general purpose programming language. It was developed by Apple and was released in 2014, making it one of the newest programming languages on the list. Despite being relatively new to the market it has many desirable characteristics that make it popular in the coding world. One of the main advantages of Swift is that it’s very safe. The language has strict coding rules which can sometimes feel restrictive. However, this makes it very easy to spot undefined behaviour and thus remove malware. Data security is an industry that is becoming increasingly important to big-business, making Swift one of the fastest growing coding languages on the market.


JavaScript has quickly become a dominant force in the coding world. It’s essential for making web pages interactive. As most users prefer greater levels of interactivity and responsiveness, many businesses are increasingly relying on JavaScript to meet that demand. This trend is likely to stay. So Javascript will remain as one of the most in-demand programming languages for years to come.


Developed in the early 70’s C is the oldest programming language included on our list. C is widely considered one of the seminal programming languages influencing the development of many other languages like Java and Python. Though C++ is now more in-demand, many employers require an understanding of C because they believe it informs the C++ and many other languages.


SQL is another industry favourite. SQL’s primary function is data flow management. If you are looking for a job in data analytics it is likely that you will need at least a basic understanding of SQL. Though it is declining in popularity today because it isn’t portable across different platforms. Languages more suited to handling big data may eventually surpass SQL in terms of popularity, but the language will always be needed for a handful of vital business functions.   


Ruby is a general purpose programming language developed by Yukihiro Matsumoto in the 1990’s. Much like Python the popularity of this language stems from its easy to understand syntax. Its ease of use is one of the reasons it is becoming popular with startups, with a “do it yourself” attitude towards web design and app creation.



Most of these languages will probably already be familiar to those within the tech industry. But the key insight to take away from a hiring perspective is that most companies are searching for candidates who are well versed in at least three or four of these languages. Very few businesses rely on one language exclusively. So tech professionals who can fill a variety of different technical niches are becoming increasingly sought-after.
