#useSetState

A React Hook that uses the React Class Component's this.setState method for state management.

#Scenes

• Closer to Developer Habits: Similar to the this.setState in Class Components, more aligned with developers' previous habits
• State Management Scenes: Implements incremental updates to the component's state without needing to replace the entire state object
• Form Handling Scenes: Manages the state of form items, supports updates to specific fields, facilitating the implementation of complex form logic
• ...

#Demo

#Usage

const [info, setInfo] = useSetState({ name: 'Bob', age: 18 }, { deep: true })

setInfo({ name: 'Amy' }) // Set new value, only updates the name field, the age field remains unchanged
setInfo({ age: 20 }) // Set new value, only updates the age field, the name field remains unchanged
setInfo({ name: 'Amy' }) // Setting the 'same' value again will not trigger a re-render. Reference to options in useSafeState.
