React Context API. How Does it Work? State Management In ReactJS (2020 Web Development)
As ReactJS Web developers, the most important part of any (more than simple)web app is state.
The normal way of handling state in ReactJS is by passing props DOWN the tree.
This works for most use cases.
In a large tree with many branches, this can get convoluted.
The React Context API lets us simplify how state is handled.
We can elevate local state to a global state so multiple components can have access to the same data.
I'll take you through creating a place to store global state, how we connect to the global state, and how we change the global state.
