Could someone explain this behavior of console.log in Chrome's dev tool? If instead of logging x I return it, I get the results you'd expect. Is this simply a bug?

EDIT:

function demo() {
  var x = [[1,1],2,3]
  console.log(x)
  console.log(x)
  console.log(x[0])
  x[0] = 42
}

Please add your code as code. – Polygnome Feb 04 '17 at 21:11
@charlietfl I would expect console.log to display the object at the point of logging, regardless of following mutations. – user2651804 Feb 04 '17 at 21:18
console isn't a snapshot of objects...they are live objects with inheritance. Stringify at time you log then will see difference – charlietfl Feb 04 '17 at 21:19
