Advanced React

React is incredibly capable and easy to use once you get past the initial learning curve, but there is so much more to it that most developers never take advantage of the more advanced features. Most often they don't know what the advanced features are, much less how to apply them properly, consistently, and to each's greatest utility. Geared for experienced React developers, Advanced React is a two-day, hands-on course designed to provide you with the skills required to take full advantage of the hidden capabilities and efficiencies that React has to offer.
