[Read more…]One of the few things that developers can agree on is that the interview process is terribly broken. There are ideas about how to fix it (links below) but the industry has yet to come to a consensus on a better way forward.
Many developers are particularly aggravated by the way some organizations insist on “academic” interview problems that test developers skill with algorithms and (big O) algorithmic analysis. The argument is that these types of problems are often irrelevant to the job, rewarding antiquated knowledge over practical skill, and are biased in favor of developers with more time and resources to spend on preparation.
Now, before we continue let me get this out of the way:
I agree with those arguments!

TL;DR: Don’t do weird stuff to JavaScript arrays.
*ahem*
In the standard definition of Array data structures in Computer Science, arrays are a collection of like elements where any member may be accessed by an index. That definition doesn’t sound very different from an Hash Table or it’s ilk, but the key distinctions here are that the elements of the array must take up the same size in memory, and that the array indexes need to be numeric so that the logical address of any individual element can be derived from that number.
