How JSX prevents Injection Attacks?

React DOM escapes any values embedded in JSX before rendering them. Thus it ensures that you can never inject anything that’s not explicitly written in your application. Everything is converted to a string before being rendered.

For example, you can embed user input as below,

const name = response.potentiallyMaliciousInput;
const element = <h1>{name}</h1>;

This way you can prevent XSS(Cross-site-scripting) attacks in the application.
