It&#x27;s not that simple I think.<p>For example, in the framework front, you guys argued that React is way better than Angular. I don&#x27;t even know what&#x27;s going on with Ember.js, Vue.js (fine, I&#x27;ll give that this one is very new and untested), Backbone+Marionette.<p>I don&#x27;t see that kind of argument in the other communities.<p>Your build: why are you omitting Grunt? What about broccoli and bower? what about Yeoman? Bower is kind of a big deal for front-end dev.<p>There&#x27;s no &quot;majority&quot; in the JS world unlike the other ecosystems.<p>Cuba? I heard Cuba _once_ in HN. Brooklyn and the rest? never heard.<p>There are bajillion newer Java &quot;microservice&quot; frameworks but the usage is just rounding error.<p>Also keep in mind that in other ecosystems, the major players are already established while in JS ecosystems, all of them are considered new&#x2F;young. There is no _established_ players for each tool segment (except unit-testing where I think Mocha is better than Jasmine, unfortunately due to lack of exposure and whatnot, Jasmine is still lurking around)
