Determining which of the world’s programming languages will succeed over the next few years is not an easy undertaking. Oftentimes, bold predictions about a language\u2019s dominance won\u2019t pan out; then you have the languages that seem to come out of nowhere to seize a significant niche (often with a bit of a boost from a major tech company). <\/p>\n\n\n\n

Every so often, though, a language\u2019s spike in popularity makes it easier to predict its rosy future. That\u2019s definitely the case with this year\u2019s list\u2026 but we\u2019ll get to that in a bit. Before we plunge into our predictions for which languages will dominate the tech industry in 2021 (assisted by a sterling panel of developers and technologists), let\u2019s hear some words of caution from Andrew Carr<\/a>, Head of Engineering at SquareFoot.<\/p>\n\n\n\n

Carr tells Dice: \u201cThe way to think about languages is not to think about what\u2019s new in 2021 compared to 2020 and which language will \u2018win,\u2019 but to think about what was true in 1999, is still true in 2020, and will remain true in 2030.\u201d<\/p>\n\n\n\n

In other words, it\u2019s all about the long term\u2014and you should structure your learning (and mastery) appropriately. \u201cI\u2019d recommend deciding what\u2019s important and building your working culture around it rather than worrying about whether you\u2019re missing out by not using a new language,\u201d he adds. \u201cIf you\u2019re an individual engineer and want to know how you can help yourself, double down on the fundamentals of how the languages you currently work in interact with the underlying operating system or runtime. A little focus on the fundamentals goes a long way here, and the fundamentals will still be the same in 2030.\u201d<\/p>\n\n\n\n

So which programming languages will continue to dominate in 2021? Here\u2019s what our panel of technologists thinks.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Python<\/strong><\/h3>\n\n\n\n

Artur Yolchan<\/a>, Senior Software Engineer<\/a> and owner of the website Coding Skills, says: \u201cPython will probably be the most favorite programming language for developers in 2021.\u201d<\/p>\n\n\n\n

The increased use of Python in a specialized context has a lot to do with that, suggests Alex Yelenevych<\/a>, CMO of CodeGym: \u201cIn the development of artificial intelligence<\/a> systems, Python has proven itself. In addition, many modern and safe sites are written in Python, and it is also very often learned in schools. The language is pleasant and quite simple for beginners, so its popularity will only grow.\u201d<\/p>\n\n\n\n

It takes a lot to erode the usage of older, more generalist programming languages, even when newer languages begin to attract a lot of buzz, adds Matt Pillar<\/a>, VP of Engineering at OneSignal: \u201cPython is an old favorite, and it\u2019s not going away anytime soon. While incumbents like Rust and TypeScript are occupying more and more mindshare, taking some attention away from Python, Python continues to be one of the most loved and most utilized programming languages. With its strong connection to data science toolkits, Python is being taught at an increasing number of programming bootcamps and is well poised to be a favorite first language for developers in the years to come.\u201d<\/p>\n\n\n\n

If you\u2019re totally new to Python, start your learning journey by heading over to Python.org<\/a>, which offers a handy beginner\u2019s guide. Microsoft has a video series, \u201cPython for Beginners,\u201d with dozens of short, Python-related lessons. There\u2019s also a variety of Python tutorials and books (some of which will cost a monthly fee) that will teach you the nuances of the programming language (and don\u2019t forget your IDEs).<\/p>\n\n\n\n

<\/div>\n\n\n\n

JavaScript<\/strong><\/h3>\n\n\n\n

Michael O\u2019Connell<\/a>, Chief Analytics Officer at TIBCO Software, doesn\u2019t think the ultra-popular JavaScript is going anywhere, especially when it comes to dominating developers\u2019 mindshare in 2021:<\/p>\n\n\n\n

\n

The maturation of JavaScript as a design and development environment has been phenomenal and will accelerate in 2021. Whether you are working on the front-end with JavaScript, apps and frameworks with React, Angular and vue.js, desktop apps with Electron.js, or backend with Node.js, JavaScript is the ticket! You can even develop machine learning<\/a> with Tensorflow.js.<\/p>\n\n\n\n

I see the worlds of self-service BI and visual analytics becoming ever more mashed up in 2021 with (a) BI and analytics vendors providing seamless experiences for extending their graphics palettes as simple-to-modify native capabilities and deployment; and (b) marketplaces for sharing extensions across broad communities of practice. The maturation of Vega (from the d3 pioneers) as a visualization grammar and platform will help standardize and enforce best practices across these communities.<\/p>\n<\/blockquote>\n\n\n\n

Yelenevych agrees, citing JavaScript\u2019s frameworks as a key component to its success. \u201cJavaScript\u2014you can find this language in use on almost every website. I think React, already the most popular JS frontend library, will continue to gain popularity. In general, developers love to create applications in React.\u201d<\/p>\n\n\n\n

Indeed, it seems virtually certain that JavaScript will continue to serve as the engine that powers the web well beyond 2021, especially as new generations of students utilize it for websites\u2019 scripted behavior. Millions of websites will still rely on third-party JavaScript libraries and frameworks. <\/p>\n\n\n\n

<\/div>\n\n\n\n

TypeScript<\/strong><\/h3>\n\n\n\n

A counterpoint to the assumption JavaScript will continue its long-term popularity comes from Pillar, who reminds us TypeScript may start eating away at JavaScript\u2019s dominance: \u201cTypeScript offers a superset of JavaScript capabilities, and was introduced to extend the utility of JavaScript. TypeScript is easier to maintain than JavaScript as a result of its type safety features and has become the go-to language for greenfield, scalable frontend applications.\u201d <\/p>\n\n\n\n

Pillar adds: \u201cWhile JavaScript is still the predominant language of the web, TypeScript is on its heels. As new applications are written in TypeScript and more and more legacy JavaScript apps are migrated incrementally, we can expect to see TypeScript surpass JavaScript in utilization in the years to come.\u201d<\/p>\n\n\n\n

Why is TypeScript so popular? With every passing version (it\u2019s now up to 4.0), it continues to add new features that developers find insanely useful. No wonder that, in the 2020 edition of the Stack Overflow Developer Survey<\/a>, some 67.1 percent of surveyed developers said that TypeScript was a programming language they loved, just ahead of Python<\/a> (66.7 percent), Kotlin (62.9 percent), and Go (62.3 percent).<\/p>\n\n\n\n

Whether or not you consider TypeScript an actual programming language (technically, it\u2019s a superset of the ultra-popular and well-established JavaScript<\/a>, but many programming language rankings treat it as a full-on language), it seems poised to dominate developer thinking in 2021 and beyond.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Go<\/strong><\/h3>\n\n\n\n

\u201cAmong working professionals, Go is the most popular aspiration language to learn by far. 32% of professional developers want to learn the language\u201d says Sachin Gupta<\/a>, CEO and co-founder of HackerEarth. Yelenevych says Go pops up with increasing regularity, making it a language to look out for in 2021.<\/p>\n\n\n\n

It\u2019s no surprise that Go is popular. It was a top paying tech skill in 2019, and has one of the best hourly rates for freelancers. Developed by Google over a decade ago as a programming language that could incorporate the best parts of other languages (such as the runtime efficiency of C++ and the readability of Python), it\u2019s enjoyed a steadily growing pool of developers who use it. In coming years, it might get even bigger.<\/p>\n\n\n\n

<\/div>\n\n\n\n

Kotlin<\/strong><\/h3>\n\n\n\n

Kotlin came up routinely in our panel discussion, and it\u2019s clear that developers are watching this language closely, especially given how Google\u2019s been encouraging its use for Android development. \u201cAndroid programming is about Java and Kotlin,\u201d Yelenevych says. \u201cThese two JVM<\/a> languages will be trending.\u201d<\/p>\n\n\n\n

Yolchan notes: \u201cKotlin is widely used for Android native app development. [Although] Android apps can be developed using Java 8, Kotlin is now the preferred language for most developers. Let\u2019s also not forget that Kotlin is a JVM-based language, and it supports all Java libraries. So, developing backend services using Kotlin also will be trending, as well.\u201d<\/p>\n\n\n\n

Google\u2019s embrace of Kotlin really accelerated things. \u201cKotlin is well positioned to absorb the mindshare that has historically been directed toward Java,\u201d Pillar says. \u201cBuilt on the JVM, Kotlin\u2019s portability gives the language large breadth, from mobile to server-side (via frameworks like Spring) to web frontends (via compilation JavaScript), Kotlin can operate in a variety of environments. Developers love features like null safety, coroutine support, and the mix of procedural and functional programming features.\u201d<\/p>\n\n\n\n

<\/div>\n\n\n\n

Which Programming Language Will Succeed?<\/strong><\/h3>\n\n\n\n

When evaluating languages that could really take off next year, there were others in the mix, including Swift, Java, and Rust. Of those three, Swift garnered the most interest, although it\u2019s largely meant to serve Apple\u2019s software ecosystem, which necessarily limits its utility in some areas. The languages listed above all had a pretty broad use-case. <\/p>\n\n\n\n

If we\u2019re picking a dark horse for a language poised for a true breakout in 2021, it\u2019s TypeScript. Not only is it really beloved, but it continues to add JavaScript features. More to the point, if JavaScript ever declines in terms of market-share and attention, TypeScript is there to instantly fill that void.<\/p>\n\n\n\n

Still, as Carr advises, don\u2019t stop upskilling your JavaScript credentials just because TypeScript is cool. There\u2019s a good chance we\u2019ll pick this discussion up in December 2021 and wonder why TypeScript never took off. Such is the world of programming languages, no matter what the year. <\/p>\n","protected":false},"excerpt":{"rendered":"
