I'm testing a library and I use console.log() function to visualyze values. There is a strange behaviour of Google Chrome (in other browser like Firefox it doesn't happend).

If I try to store strings in Array object when I log them, sometimes values appears undefined.

Code example (item.name is a string)

var arrayItemsSearch = [item.name];
var itemRedrawName = [item.name];
console.log("arrayItemsSearch: ", arrayItemsSearch);
console.log("itemRedrawName: ", itemRedrawName);

Firefox output is correct

arrayItemsSearch: ["elem[0]"]
itemRedrawName: ["elem[0]"]

Chrome output is not correct

arrayItemsSearch:  [undefined × 1]
itemRedrawName:  ["elem[0]"] 

Is this a Chrome bug? Or is this beacuse in Javascript strings are immutable objects and so something that I don't understand goes wrong?
