s/can/should only contain numeral indices. Arrays as just objects so they
can indeed
contain anything, and inherit functions. Also note that a for-in loop on
arrays will return
the keys as strings, not numbers:
`var a = ['foo', 'bar']; for (var b in a) {}; console.log(typeof b, b /*
"string", "1" */);`
