Read moreWhat are reactions in MobX?
Reactions are an important concept to understand, as it is where everything in MobX comes together. The goal of reactions is to model side effects that happen automatically . Their significance is in creating consumers for your observable state and automatically running side effects whenever something relevant changes.

In The gist of MobX you have already seen the most important part of this integration: the observer HoC that you can wrap around a React component . observer is provided by a separate React bindings package you choose during installation.
