title: Is Splice faster than Shift + Pop? Why?
body: <p>I've heard from some nonspecific sources that using a combination of <code>shift()</code> and <code>pop()</code> is faster than using <code>splice()</code>. I haven't run a benchmark test yet and will most likely not for a while since I'm out of town, but is this true, and if so, why?</p>
