🔍 What is useRef?

useRef is a built-in React hook that helps you:

1. Access and interact with DOM elements directly.

2. Store mutable values without causing re-renders.

📦 How to Use useRef in React

First, import it:

import { useRef } from 'react';

✅ 1. Accessing DOM Elements

A common use case is focusing an input field:

import React, { useRef } from 'react';

function FocusInput() {
  const inputRef = useRef(null);

  const handleClick = () => {
    inputRef.current.focus(); // Focuses the input
  };

  return (
    <>
      <input ref={inputRef} type="text" />
      <button onClick={handleClick}>Focus</button>
    </>
  );
}

inputRef.current points to the actual HTML element!

✅ 2. Keeping Mutable Values

Sometimes, you need to store a value that changes but doesn't cause a re-render.

import React, { useRef } from 'react';

function ClickCounter() {
  const count = useRef(0);

  const increment = () => {
    count.current += 1;
    console.log('Clicked:', count.current);
  };

  return <button onClick={increment}>Click Me</button>;
}

Unlike useState, changing count.current won’t re-render the component.
