dangerouslySetInnerHTML Prop in React

Setting HTML from code can lead to exposing your users to a cross-site scripting (XSS) attack. In case your are setting HTML from your code, you can intentionally set it as dangerouslySetInnerHTML and pass an object with a __html key, to remind yourself that it’s dangerous.

<div
  dangerouslySetInnerHTML={{
    __html: '<h1>Hello World</h1>'
  }}></div>
