What is virtual Dom. Security in react

Question

Accepted Answer

Virtual DOM security in React refers to the protection of the virtual representation of the DOM from potential security vulnerabilities.

Virtual DOM in React is a lightweight copy of the actual DOM, which allows React to efficiently update the UI without directly manipulating the real DOM.
Security in virtual DOM involves preventing cross-site scripting (XSS) attacks by sanitizing user input and using libraries like DOMPurify.
React's reconciliation process ensures that only the necessary DOM updates are made, reducing the risk of security vulnerabilities.
Avoiding direct DOM manipulation in React components helps maintain security by preventing injection attacks.
