Hello everyone,
Im new to react hooks
Currently I am dealing with a problem where I have to use the previous state inside of a useEffect hook.
useEffect(() => {buttonEvent$.pipe(skip(1)).subscribe(({value, type}) => {handleButtonEvent(value, type);});return () => {buttonEvent$.unsubscribe();}}, []);
In the above example, I need to access previous state inside of handleButtonEvent method.
how can I do this ?
if (operator === '') {setOperandOne((prevState => { return {...prevState, value: `${prevState.value}${value.name}`}}));} else {setOperandTwo((prevState => { return {...prevState, value: `${prevState.value}${value.name}`}}));}
A snippet of code inside the handleButtonEvent method, I need to use a if condition based on the state of operator . But it is always the initial value only.

Hey guys, I have a dialog that's supposed to show on button click, and close when close btn is clicked inside dialog
this is my state and the function that mutates the state
this is the button responsible for showing the dialog which works and the dialog shos
shows*
this is the rendering function that renders the dialog only when criteria is true, inside it there's a cancel btn that's supposed to close the dialog and set the state to false
it doesn't work
but when I bind the ShowFiltersUI to a btn outside SearchFiltersPopup div it works just fine
Idk where's the problem
