JSX
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. This helps prevent XSS (cross-site-scripting) attacks.
Design simple views for each state in your application, and React will efficiently update and render just the right components when your data changes.
React DOM compares the element and its children to the previous one, and only applies the DOM updates necessary to bring the DOM to the desired state.

Reactjs is the best for creating engaging and interactive user interfaces for mobile and web applications.
Some of the core features of Reactjs, such as a virtual DOM and server-side rendering, help in creating large-scale and complex apps that run incredibly fast.
