Why Can Hooks Only Be Called Within The Body Of A Function Component In JavaScript?

This error occurs when you try to use a hook (such as useState, useEffect, etc.) outside of a functional component in React.

In React, hooks can only be used inside the body of a function component or another custom hook. You cannot use them in regular JavaScript functions, class components, or in any place other than the top level of a function component.

To fix this error, make sure you are using the hook inside a functional component. Here’s an example:

import React, { useState } from 'react';

function MyComponent() {
  const [value, setValue] = useState('initial value');

  return (
      <p>Value: {value}</p>
      <button> setValue('new value')}>Update</button>

In this example, useState is used inside the body of the MyComponent function, which is a functional component. The error will no longer occur because hooks are being used correctly.
