why is my `useEffect` hook still running multiple times even with a correct `dependency array`?

  • hey folks, just trying to fix this wierd behavior with a useEffect hook that keeps firing.

  • even after setting up the dependency array correctly, it's still running on every component re-render or more often then expected, which is super annoying.

  • here's a quick code snippet of what i'm doing:

    import React, { useEffect, useState } from 'react';
    
    function MyComponent() {
      const [value, setValue] = useState(0);
    
      useEffect(() => {
        console.log('useEffect fired!');
        // some async operation perhaps
      }, [value]); // this is the dependency array
    
      return (
        

    Current value: {value}

    ); }
  • anyone faced this before? it's really holding up my progress.
