how to not execute useEffect when loading the page first time

//This is a way to build this effect as a custom hook
import React, { useEffect, useRef } from 'react';

const useDidMountEffect = (func, deps) => {
    const didMount = useRef(false);

    useEffect(() => {
        if (didMount.current) func();
        else didMount.current = true;
    }, deps);
}

export default useDidMountEffect;

                                    const { useState, useRef, useLayoutEffect } = React;

function ComponentDidUpdateFunction() {
  const [count, setCount] = useState(0);

  const firstUpdate = useRef(true);
  useLayoutEffect(() =&gt; {
    if (firstUpdate.current) {
      firstUpdate.current = false;
      return;
    }

    console.log(&quot;componentDidUpdateFunction&quot;);
  });

  return (
    &lt;div&gt;
      &lt;p&gt;componentDidUpdateFunction: {count} times&lt;/p&gt;
      &lt;button
        onClick={() =&gt; {
          setCount(count + 1);
        }}
      &gt;
        Click Me
      &lt;/button&gt;
    &lt;/div&gt;
  );
}

ReactDOM.render(
  &lt;ComponentDidUpdateFunction /&gt;,
  document.getElementById(&quot;app&quot;)
);

Thank you! 0
