"null" and "undefined" printing in the Drosera console are poor var x = undefined undefined x // nothing prints var y = null undefined y // nothing prints var z = "undefined" undefined z undefined This is all very confusing. I would expect "undefined" and "null" to be special values and print the string "undefined" or "null" when printed. Some sort of special (styled) .toString() behavior for the Drosera console.
Not an issue in the Web Inspector's debugger and the Inspector's console.
