A simple Vue project can be run directly from a browser with no need of transpilation. This allows Vue to be easily dropped into a project the way jQuery is.While this is also technically possible with React, typical React code leans more heavily on JSX and on ES6 features like classes and non-mutating array methods.

I just created an empty Rails project and just find node_modules -print | wc -l gives me 18366 files!

Why include that six-line helper function when you can do a one-line `require`? Never mind that the required module has its own dependencies, with their own dependencies, until your users suddenly find that `npm install` involves downloading 70Mb of gubbins split into 15,000 files. I exaggerate, but barely.
