React is often mentioned in the same breath as other Javascript frameworks, but "React vs Angular" doesn't make sense because they aren't directly comparable things. React gives you a template language and some function hooks to essentially render HTML. You absolutely cannot build a fully functional dynamic application with React alone. The Good After working with React for a while, I've seen three very important benefits surface. 1. This may be the most important benefit, even though it is not different from Angular templates. Say you have to update your site's header with the user's name upon log in. Here's how you might do it in React: 2. 3. The Bad

Frameworks like Ruby on Rails provide a lot of features out of the box - in fact the problem you may have with JavaScript is caused by that.

Try clicking on "Compiled JS" to see the raw JavaScript code produced by the JSX compiler.

Static Site Generation with React and Webpack I’ve been dabbling with React for a few months now and using it in several small open source projects to better understand the technology. React’s focus on reusablility, along with the ability to install and require components via npm, provides an elegant way to rapidly build application UI in an efficient and consistent way. It’s also a great way to handle server-side rendering and provides high cohesion between markup and display logic. Note: many of the packages referenced in this post have released major version, breaking updates since this was written. Some of the examples may not work with the latest npm modules, especially the react-router package, which has a much different API now. Why
