If Array keys are actually strings, then what differentiates an Array from an Object?

Question

I mean, apart from the [].prototype methods and the strictly-"stringmeric" keys?

Anything?

Could an array said to be an object that by convention has exclusively "numeric" string values as keys, and inherits methods from Array.prototype?

Are there any other differences?

Maybe [this question](http://stackoverflow.com/questions/874205/what-is-the-difference-between-an-array-and-an-object) helps. — Sascha Wolf, Nov 26 '13 at 14:26

The key difference is the automatic behavior of the .length property.

You get the Array prototype such as

$ ['foo', 'bar'].length
2

$ ['foo', 'bar'].join('|')
'foo|bar'

// etc...
