— Heh, you're the only person I know that optimizes by adding complexity

— 

Whenever I design algorithms they tend to get really fat before they get smaller, I do a lot of refactoring after I make a (usually too complex) minimally functional example

— This thing *used* to be a thunk, now it's some magical thing...

// Formats & inserts data into `templDocs`, then inserts it into `destElems`.

function insertionThunk(templDoc) {

  var templDocs = [templDoc];

  if (conf.paged && conf.elemPerPage > 1) {

    for (var loc = 0; loc <= conf.elemPerPage; loc++) {

      templDocs[templDocs.length] = templDoc.cloneNode(true);

    }

  }

   return insertTemplates(injectData(templDocs, conf), destElems, conf);

}

— Push is extremely slow

— Never use push when you need performance

— Huh

— Interesting

— Also length on arrays is the same as storing your own variable, no overhead at all

— Well, only if you're modifying it

— I mean, for reading
