react. too many re-renders. react limits the number of renders to prevent an infinite loop

 

문제상황 : too many re-renders. react limits the number of renders to prevent an infinite loop  발생 

  const nextPlease = () =>  
    setBack(false);
    setVisible((prev) => (
      prev === 10 ? 10 : prev + 1
    )
   );
  const previousPlease = () => 
    setBack(true);
    setVisible((prev) => (
      prev === 1 ? 1 : prev = 1
    )
  );

 

해결 :

해결방법은 단순했다. 괄호가 안 닫힌 것이 이슈였다. nextPlease와 previousPlease를 모두 {}로 닫아주니 해결되었다. 

  const nextPlease = () => {
    setBack(false);
    setVisible((prev) => (prev === 10 ? 10 : prev + 1));
  };
  const previousPlease = () => {
    setBack(true);
    setVisible((prev) => (prev === 1 ? 1 : prev - 1));
  };
