Steps to reproduce:

1. Run the following code:

    function fillConsole(n) {
        var pre='', o={}, tmp;
        for(var i=0; i<n; ++i) pre+= String.fromCharCode(i%95+32);
        for(var i=1; i<=10; ++i) o[tmp = pre+i] = tmp;
        console.log(o);
    }

2. Have fun calling it with a big number, e.g., 

    fillConsole(1e5);


Actual results:

The console is filled with a huge amount of data.


Expected results:

There should be some limit!

I think objects shouldn't take more than one or two lines. Displaying object's data is only useful for small ones; but for big ones there's no point in displaying all data in an unreadable way: if someone wants to explore them, he can click to explore them well at the right subpanel.
