Web Development with Node.JS and MongoDB (Video 38)

This video tutorial introduces isomorphic applications, which allow the same code to run on both the server and client, reducing duplication. It highlights benefits such as improved SEO and performance. The video explains how to use React to build isomorphic applications, detailing the process of rendering and context checking. It concludes with a brief introduction to Webpack, which will be covered in the next video.

What is a key feature of isomorphic applications?

• They require no validation logic.
