Annotated Underscore.js Source Code – Good for Budding JavaScript Developers

I love the annotated source code, but I wouldn't necessarily recommend the Underscore library code itself as learning material to budding developers - it's optimised for size and performance, not legibility and idiomatic style. I remember being a budding JS dev once upon a time, and being quite perplexed by it :)

Also interesting, even if it has become unfashionable these days, Backbone&#x27;s annotated source: <a href="http:&#x2F;&#x2F;backbonejs.org&#x2F;docs&#x2F;backbone.html" rel="nofollow">http:&#x2F;&#x2F;backbonejs.org&#x2F;docs&#x2F;backbone.html</a><p>And the tool to make these: <a href="http:&#x2F;&#x2F;ashkenas.com&#x2F;docco&#x2F;" rel="nofollow">http:&#x2F;&#x2F;ashkenas.com&#x2F;docco&#x2F;</a>

For beginners annotated code of highly optimized library might become confusing. Try reading Mary Rose Cook&#x27;s annotated code of 2 JS games and a Git clone <a href="http:&#x2F;&#x2F;annotated-code.maryrosecook.com&#x2F;" rel="nofollow">http:&#x2F;&#x2F;annotated-code.maryrosecook.com&#x2F;</a>

Probably a bit long in the tooth now:<p><a href="http:&#x2F;&#x2F;robflaherty.github.io&#x2F;jquery-annotated-source&#x2F;" rel="nofollow">http:&#x2F;&#x2F;robflaherty.github.io&#x2F;jquery-annotated-source&#x2F;</a>

Line 6: Naked function reference for surrogate-prototype-swapping. var Ctor = function(){};<p>TIL Ctor is short for constructor (?)

Very nice! Even those of us who don&#x27;t consider ourselves &quot;budding&quot; have plenty to learn here.

How did you go about creating this? I think it&#x27;s super useful way of documenting code in general!

This is amazingly helpful. Thank you for posting!
