Peeking a bit under the hood, it appears to be due to transitive dependencies referencing github urls (and transient ones at that) instead of semver, which admittedly is neither standard nor good practice... FWIW, simply removing `"grunt-contrib-jshint": "~0.4.3",` from package.json and related jshint-related code from Gruntfile was sufficient to get `npm install` to complete successfully. The debugging just took me a few minutes grepping package-lock.json for the 404 URL in question (https://github.com/ariya/esprima/tarball/master) and tracing that back to a top-level dependency via recursively grepping for dependent packages. I imagine that upgrading relevant dependencies might also do the trick, seeing as jshint no longer depends o

In general there are two types of JS code bases you'll encounter, the ones for the Browser which end up putting everything into a single file and the ones for Node.js, which (in most cases) organize their code in the usual directory / file structures you may be used too from other programming languages. There are also multiple camps which battle about whether too use semicolons at all and where to place commas that separate the individual parts of `var` statements. I'm not going to take any sides here, since I think that style is something everyone has to decide on their own :) Now as for the code to read, there's obviously jQuery, but Angular.js is definitely a good read too these days. https://github.com/angular/angular.js If you're into parsing (or want to learn about it), there's also Esprima which is a JavaScript Parser written in Ja
