React useContext

This lesson is part of React · All levels

Summary

UseContext reads the value of React Context without having to write the layered Consumer component. You create context with createContext, wrap the application part with the Provider, and then read the value in any component through useContext. This pattern is suitable for themes, languages, and user data that use multiple components.

Key points

CreateContext creates context along with its sub-values
The provider sets the value for all of his descendants
Take the nearest Provider value
Reducing prop drilling on many component levels
