[Solved]-React.js: Set innerHTML vs dangerouslySetInnerHTML-Reactjs

Yes there is a difference b/w the two: dangerouslySetInnerHTML: React diffing algorithm (https://reactjs.org/docs/reconciliation.html) is designed to ignore the HTML nodes modified under this attribute thereby slightly improving the performance. If we use innerHTML, React has no way to know the DOM is modified. The next time the render  happens, React will overwrite the content that was manually injected with what it thinks the correct state of that DOM node should be. That's where componentDidUpdate comes to rescue!

Based on (dangerouslySetInnerHTML).

It's a prop that does exactly what you want. However they name it to convey that it should be use with caution

According to Dangerously Set innerHTML,

Improper use of the innerHTML can open you up to a cross-site scripting (XSS) attack. Sanitizing user input for display is notoriously error-prone, and failure to properly sanitize is one of the leading causes of web vulnerabilities on the internet.

Our design philosophy is that it should be "easy" to make things safe, and developers should explicitly state their intent when performing “unsafe” operations. The prop name dangerouslySetInnerHTML is intentionally chosen to be frightening, and the prop value (an object instead of a string) can be used to indicate sanitized data.

After fully understanding the security ramifications and properly sanitizing the data, create a new object containing only the key __html and your sanitized data as the value. Here is an example using the JSX syntax:

function createMarkup() {
    return {
       __html: 'First · Second'    };
 }; 

<div dangerouslySetInnerHTML={createMarkup()} />

You can bind to dom directly

<div dangerouslySetInnerHTML={{__html: '<p>First &middot; Second</p>'}}></div>
