Its converted to string first, see spec
at http://www.ecma-international.org/ecma-262/5.1/#sec-15.12.2
For example, this results in [1, 2, 3] array :
> var qqq = {}
undefined
> qqq.toString = function () { return "[1, 2, 3]"; }
[Function]
> JSON.parse(qqq)
Buffer.toString is defined
here:
https://github.com/nodejs/node/blob/c41c09375b217d9daec614edb590147b14ff9b21/lib/buffer.js#L405
By default, its "return string using buffer bytes and interpreting them as
utf8 sequence"
