Detached DOM nodes
View detached
// create an element to attach to document
var d = document.createElement('div');
// take heap snapshot and filter on 'detached' will show the above node
// now attach element to document
document.body.appendChild(d);
// take heap snapshot and the detached node is no longer listed
// you can look at diff between two snapshots and see it has been added to HTMLBodyElement

You can’t perform that action at this time.
