import React, { useState, useEffect, useRef, useContext, useReducer, useMemo } from 'react'; export default Effects = () => { const [count, setCount] = useState(0); useLayoutEffect(() => console.log("each render 1")); console.log("each render 2"); useEffect(() => console.log("each render 3")); return ( <> <button onClick={() => setCount((prevProps) => ++prevProps)}> Increment </button> </> ) }

In this React component, the following occurs on each render:

1. First, useLayoutEffect is called, which runs synchronously after all DOM mutations but before the browser repaints. "each render 1" is logged to the console.

2. Then, the main function code of the component executes, where console.log("each render 2") is called — it runs on every invocation of the component function, i.e., on every render.

3. After the browser finishes rendering, useEffect runs, logging "each render 3".

Thus, the order of logs on each render will be:

• "each render 2" (during render)
• "each render 1" (in useLayoutEffect)
• "each render 3" (in useEffect)

Clicking the Increment button calls setCount, which triggers a re-render and repeats the cycle.

Important: There is an error in the code — useLayoutEffect is not imported from 'react', and the component is declared without the function or const keyword. Correct import and declaration:

import React, { useState, useEffect, useLayoutEffect } from 'react';

const Effects = () => {
  const [count, setCount] = useState(0);

  useLayoutEffect(() => console.log("each render 1"));

  console.log("each render 2");

  useEffect(() => console.log("each render 3"));

  return (
    <>
      <button onClick={() => setCount(prev => prev + 1)}>
        Increment
      </button>
    </>
  );
};

export default Effects;

Also, it's better to use prev + 1 instead of ++prevProps inside setCount.
