React.js error “ Expected corresponding JSX closing tag ” appears when we forget to close a tag in the JSX code . To fix the error, use self-closing tags like <input />and make sure the order of opening and closing tags in the JSX code is correct.

Here is an example that produces the above error

export default function App() {
  // ⛔️ Expected corresponding JSX closing tag for <input>.
  return (
      <div>
        <h1>Hello world</h1>
        <input id="icon_prefix" type="text" class="validate">
      </div>
  )
}

The problem in our example is that we forgot to close the tag of the input element.

We can use self-closing tags to fix the error.

export default function App() {
  return (
    <div>
      <h1>Hello world</h1>
      <input id="icon_prefix" type="text" class="validate" />
    </div>
  );
}

We used a self-closing tag for the input element. So instead of using , which caused the error <input>, we used <input />.

This error is also commonly caused by img elements. Make sure to always close our img tags as <img src="..." />.

<br />The same is true for the and <hr />tags.

We always have to close the tag or use a self-closing tag, otherwise React expects us to pass the children prop to the component.

It can also cause errors when we open and close tags in an incorrect order.

export default function App() {
  // ⛔️ Expected corresponding JSX closing tag for <input>.
  return (
    <div>
      <h1>Hello world
      <span>Hello 123</h1></span>
    </div>
  );
}

The problem in the code snippet above is that h1the <div> tag opens, then spanthe <div> element begins, and then h1the <div> tag spancloses before the <div> element.

To fix the error in this case, we must first close spanthe tag.

export default function App() {
  return (
    <div>
      <h1>
        Hello world
        <span>Hello 123</span>
      </h1>
    </div>
  );
}

Always use closing or self-closing tags because if React finds only an opening tag, then it expects us to childrenpass the attribute to the element and then close it.
