jQuery html vs append

Question

Lets say I have an empty div:

<div id='myDiv'></div>

Is this:

$('#myDiv').html("<div id='mySecondDiv'></div>");

The same as:

var mySecondDiv=$("<div id='mySecondDiv'></div>");
$('#myDiv').append(mySecondDiv);

Answer 1

html() will completely replace the content inside the tag that the selector corresponds to. $('#'). append() will just append to the end of the content inside the tag.
