Component not showing data after useRef

Hello,

A little explanation before the code:
I am fetching data from a database asynchronously. Fetches just fine using the function

fetchData

fetchData

. Then to stop continuous re-rendering I use useRef instead of useState to set two arrays

cdata

cdata

and

pdata

pdata

. Their

console.log

console.log

shows it worked.
However, when I call my component after

onclick

onclick

neither

cdata

cdata

nor

pdata

pdata

are available.
I cant use

useEffect

useEffect

as I need my data to be available after

onclick

fetchData

fetchData

useEffect

onclick

onclick
