Netflix Replaces React with Vanilla JS

Netflix made a notable optimization by replacing some parts of its React-based front end with Vanilla JavaScript, particularly on its landing page. This move significantly reduced the JavaScript bundle size by about 200KB, resulting in a 50% decrease in load times. Netflix still uses React for server-side rendering, but this blend of technologies ensures a more efficient and faster-loading client-side experience. This approach highlights the importance of choosing the right tool for the right part of a web application to enhance performance.
