React Performance Tune-Up

At our recent engineering offsite my team took the opportunity not only to plan out and design some new features we’re starting to build but we also spent some time tuning our existing React application to make it even faster. Here are a couple of the quick wins we had and a few additional techniques that might help you spot bottlenecks and tune up your own app. You can’t tune what you can’t measure, so a large part of any performance effort is properly instrumenting both your application and your testing environment to measure and analyze the deltas as you work.
