(after The Raven)
Once upon a midnight dreary, while I struggled with JQuery,
Sighing softly, weak and weary, troubled by my daunting chore,
While I grappled with weak mapping, suddenly a function wrapping
formed a closure, gently trapping objects that had gone before.
Ah, distinctly I remember, it was while debugging Ember,
As each separate dying member left its host for ever more.
Eagerly I wished the morrow–vainly I had sought to borrow
(From my bookmarked trail of sorrow), APIs from Underscore.
There I sat engaged in guessing the meaning of each cursed expression,
Endless callbacks in procession; nameless functions, nothing more,
This and more I sat divining, strength and spirit fast declining,
Disclose the value we’re assigning! Tell me - tell me, I implore!
