Question

I want to dump this array to string and get the same object after evaluating it.

arr = [5, 86, function() { console.log(arguments); }, [console.log, 357]];

Although, functions may have extra properties, only the code is necessary to reproduce.

I can’t find a way to do this in Node:

> console.log(arr)
[5, 86, [Function] [ [Function], 357] ]

> util.format('%j', arr)
'[5,86,null,[null,357]]'

> arr.toString()
'5,86,function () { console.log(arguments); },function () {\n  process.stdout.write(util.format.apply(this, arguments) + \'\\n\');\n},357'

The latter has flatterned the array.

Is there a better way?

update: found the satisfying solution, see my own answer.
