What does 0:({}) mean in object dump in Mozilla Firefox
firefox, javascript, object
Solution
Because `{}` could also mean an empty block, for example: in the console, you need to type `({})` to mean an object.
Problem
I dumped an object in Mozilla and I got the following: ``` ({ length:1, prevObject:{0:({}), context:({}), length:1}, context:({}), selector:"ROOT", 0:({}) }) ``` What does `({})` mean in object notation? I understand that `{}` means an object but what do the round braces signify?
