Which programming languages will dominate the tech industry in 2021? What are some important trends you should be looking out for in the coming new year?
OneSignal’s VP of Engineering, Matt Pillar, was recently featured by Dice Insights, providing his insight and predictions on the world’s most popular programming languages. And while there are a plethora of languages to be thinking about, here are the 4 most in-demand languages that our team thinks should be included at the top of your list come 2021:
In the context of high performance applications and distributed systems, Rust has huge momentum. We continue to see projects that historically would have been authored in C++, now being built in Rust to be used at scale. Developers love features like the memory-safe type system offered by Rust, and in fact, Rust was ranked as the top most-loved language in the Stack Overflow 2020 survey. The Rust community is booming. At this year’s RustConf, which was operated completely online, the Rust Core Team doubled down on their message that Rust is designed to empower all developers, helping to build a more inclusive community.
Rust enables OneSignal to build robust, complex systems quickly and fearlessly, thanks to its powerful type system and ownership rules. After 4 years of Rust at OneSignal, we have been able to use Rust to send over 8 billion push notifications each day and we continue to be one of its highest-scale Rust applications in the world. Learn more about Rust at OneSignal and check out our podcast on Scaling Rust starring Joe Wilm, CTO of OneSignal.
TypeScript has helped OneSignal maintain its rapid pace of development while drastically scaling our product and engineering team. Through features like transpile time error checking and strong typing, we are able to both easily refactor our code and prevent many classes of bugs. Read more about how OneSignal has modernized our frontend using TypeScript.
OneSignal’s Android SDK 4.0 is now live, with upgrades to AndroidX, Swift, and Kotlin nullability, and more. Learn about OneSignal’s latest major Upgraded SDK Release, now available for iOS and Android.
Python is an old favorite, and it’s 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 top 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.
On to 2021
