React compression

An app’s bundle size is the amount of JavaScript a user will have to download to load your app . The bigger the bundle size is, the longer it will take before a user can view your app. If this gets too slow, it can lead to frustration for your users, especially those with slower internet connections.

Being part of the React community for a while, you start to notice patterns. The common themes. The perennial struggles. There are the nuts and bolts problems: immutability is weird; JSX isn’t always intuitive; “thinking declaratively ” is a hard-won skill.

If you have these skills already, then learning React should be a relatively straightforward process . It has its own unique set of challenges, but it is an excellent tool to have in order to start or further your career as a web developer.

The biggest nonobvious part of React is probably the events system — not only does React implement its own event dispatching and bubbling, it normalizes common events across browsers so that you don’t need to worry as much about it.6 Kas 2013
