The rise of React
Props to the people who have been managing the project. I have done a lot of React in the last 6 years and have never been frustrated with their decisions, which is very rare.<p>I think beyond the technical aspects, the way React evolved over time was really on point. The roadmap has always been very well designed and the literature around new features and deprecated ones top notch.<p>The way React is used has changed completely, but at no point did I feel upgrading was too costly and ended up stuck with an old version.
