There’s no doubt which programming language is winning the battle for global supremacy right now. JavaScript has powered past the 12 million developers mark, and 5 million of its loyal fans (some 40%) have come aboard within the last three years. Initially thought of as merely a Java spin-out, it is now used to power everything from machine learning libraries to space exploration robots. But to truly maximize the potential of JavaScript, developers have to implement an effective testing regime.

While humans are ever-adapting, the recent pandemic has forced a complete revamp of how we work and play. As in-person meetings and conventions remain sparse, networking in other ways has become a new normal. Mobile app developers are applying key lessons and trends of online networking and socializing to capitalize on increasing global demand for virtual connectivity.

It’s no exaggeration to say that today’s internet is built on JavaScript. Around 95% of all websites have been built using the language, according to the latest figures. JavaScript has evolved beyond the client side and is now used to construct entire technology stacks, not to mention support databases like pouchdb and RethinkDB.

The device landscape is as vast as it is complex. With at least 63,000 possible device profiles reported—a number growing at almost 20% per year—the scale of device fragmentation is staggering. New models, operating systems, browsers, screen resolutions, etc., make it extremely difficult for web and app developers to deliver a consistently flawless user experience across all combinations.

Two of the most useful tools for making software development run smoothly are CI & CD. Over the years our stack has evolved from a humble Jenkins box into a cloud-native platform. In this post, we’ll share our learnings from this journey.
