JS RemoveChild method to understand _javascript skills in depth

1. Overview

The deleted node, although not in the document tree, is still in memory and can be added to another location at any time.

When you traverse a child node of a parent node and perform a delete operation, note that the Children property is a read-only property and is updated in real time when the child nodes change

Get the node to delete:
var self = document.getElementById (' to-be-removed ');
Get the parent node:
var parent = self.parentelement;
Delete:
var removed = Parent.removechild (self);
removed = = self; True
