Also the rate of breaking changes with react is pretty intense. While you can author react without a build tool, and I certainly am using webpack with vue myself, your same vue know how also works for spots where you may not have a build tool available, like freelancing updates to wordpress for people for side money. In those cases you're stuck sticking js into a CMS editor. But vue has you covered in all scenarios from the complex app with webpack and vuex to simple reactive code entered into a cms editor without the benefit of a build tool.
