This article explains this knowledge, for more information, see where I can see process for the first time. nextTick is called. Oh, it should be seen in the official process document of nodejs. At that time, I

the previous sibling node of a node.AppendChild cannot set the explicit position//otest.appendchild (oP2) you want to insert; InsertBefore can be set//otest.insertbefore (Op2,null);//otest.insertbefore (OP2,OP1);//otest.insertbefore (OP2, op1.nextsibling);//otest.insertbefore (op2,op3.previoussibling);//otest.insertbefore (OP2,oTest.childNodes[0]);All right, so there's insertbefore, and there's InsertAfter , right?Well then let's write an example wit

use VM. createscript. First, prepare a file named example. js in the root directory of your node (generally 'C: \ Program Files \ nodejs').
