JSX Elements Must be Closed

In JSX, elements must be closed, even if they don’t have any content inside. This is to ensure that the code remains valid and consistent.

Self-closing tags: For elements that don’t have any content, you should use self-closing tags. In JSX, self-closing tags are written with a slash / before the closing angle bracket >. Here’s an example:

import React from 'react';

function MyComponent() {
  return (
    <div>
      <input type="text" />
      <img src="image.jpg" alt="Image" />
      <br />
    </div>
  );
}

In this example, the <input> and <img> elements are self-closed with the / before the closing angle bracket. The <br> element, which is an empty line break, is also self-closed.

Closing tags for elements with content: For elements that have content, you need to include both the opening and closing tags. Here’s an example:

import React from 'react';

function MyComponent() {
  return (
    <div>
      <h1>Hello, JSX!</h1>
      <p>This is a paragraph.</p>
    </div>
  );
}

In this example, the <h1> and <p> elements have opening and closing tags to enclose their respective content.

Remember to always close JSX elements, either with self-closing tags or with both opening and closing tags, based on whether they have content or not.
