I'm not really versed on JavaScript. I presume this is a joke about the lack of a proper array structure in JavaScript? How would one answer this question anyway?
This is probably intended to be a joke about how Javascript was originally developed over about 10 days, which has been the root of many of JS's problems.
While it's probably joke, JavaScript's Array is fine (although it's more like a 'vector'). JavaScript VMs implement it as a real array (in fact, plain objects are often optimized into arrays too).
