This also works:
function destructedDefaults({foo="default"}={}) { return foo; }
Nice, but what's the purpose of the second curly brackets?
Well, it is the default for the first argument. So you can call the function with no argument. If it wouldn't be there, calling it without an argument, destruction leads to a TypeError of can not access property 'foo' of undefined.
can not access property 'foo' of undefined
Okay cool
