Today's users demand highly interactive web content. To deliver that content, it's critical your code can scale to accommodate your burgeoning featureset.
Before functional programming UI libraries like React, user interfaces were built using an imperative style. This meant that applications were highly succeptible to unintended side effects which caused headaches for developers and product owners alike.
With React, your user interfaces scale with you. Rather than being rewritten, we'll write code that's ready for reuse in multiple contexts throughout your user interface. And because React is functionally-oriented, it's also easy to write automated tests, meaning your code will be constantly evaluated before bugs get to your users.
