How can we delete specific child <div> inside the parent <div> tag?

If you have this code for example 

<div id="parent">

<div>div one</div>

<div>div two</div>

<div>div three</div>

<div>

you have may way to delete aby element by using .removeChild() in javascript

var divList=document.getElementById("parent");

//i is the index of the element

var i=0divList.removeChild(divList.childNodes[i]);

you can use jqury .children() with .remove()

by jQuery :

according to "Khadijah Shtayat"  example you can try

$("#parent").children("div").remove();

What if we have Appended the <div> tag ?
