June Highlights

React reached new heights in June with a mention in over 28% of postings, easily taking the top spot for the thirteenth month in a row. The highest ever for a technology was 32% for JavaScript nearly four years ago. Can React challenge it? With React's adoption on the web and for mobile app developments with React Native, it presents an attractive platform for many developers to explore. But, front-end technologies have a history of being replaced for the hot new thing, so how long can React stay on top?

Recent notable movers, Node.js (into the top 5 last month) and Go (first top 10 appearance 2 months ago), could not continue their climbs, and have leveled off a bit, though still near their peaks.
