What if you need to manage more complex states? Here useReducers comes into play
React Hooks are so powerful and especially some additional hooks.
Do you know there is an alternative to useState called useReducer hook? It is used to manage more complex states.
Let's look into detail 🧵👇🏻
What if you need to manage more complex states? Here useReducers comes into play
The second value is a dispatch function using which we can update our state.
Here is the complete syntax 👇🏻
I just implemented a basic code here. Basically, I am calling dispatch function on button click which will eventually call reducer function
Before that one thing to note here is that useReducer is for handling more complex states hence it is recommended to passing the current state as an object
Something like this 👇🏻

Here is "payload" comes into play. It is used to pass the value which represents the payloads of the action.
For example, suppose I want to pass "temp" variable 👇🏻
