Reading the page then the comments, even as a senior developer who only touches JavaScript when necessary; I don't see much unification in the JavaScript world today compared to 12 to 15 years ago.

React seems to be a theme, if I want to develop a modern (is Web 2.0 still the term) single-page site (is that still a phrase?) using HTML5/CSS3/JavaScript...what environment exists that is cohesive and complete as either Eclipse for Java or Visual Studio for .NET?

Here's my answer, as an outsider, Java dude who only suffers brief interludes with JavaScript...I'd pick jQuery Mobile or DART.

The thing is...whenever these JavaScript tooling articles comes up I don't see those listed. I see names like React, Meteor, Gulp, Grunt, Webpack and maybe 3 dozen more.
