How would that be?
x= y= {}
[object Object]
o= {x:x}
[object Object]
free(x)
true
typeof x
??
typeof y
??
typeof o.x
??
Or:
(function () {
function ƒ () {}
setTimeout(ƒ, 1000)
free(ƒ)
})()
?
When would be the right time to free(something)?
What would `something` be after the call to free(), null?
What if `something` isn't the only reference to the thing?
Would it be ok to null somebody else's references?
If not, what exactly would free(thing) do?
