What is the difference between and in JavaScript

Question

I came across this query and am considering the similar issue in JavaScript.

When creating strings in JavaScript, using the character'or the character " seems to have no effect on how the application functions. What distinguishes these two characters from one another, then?

The only benefit I can think of for using'to construct strings is that I can do things like

var toAppend = '<div id="myDiv1"></div>';

Instead of:

var toAppend = "<div id=\"myDiv1\"></div>";

Is there any significant difference between them that I should be aware of?
