Answer 1

Single and double quotes do the same thing in JavaScript: they limit string constants. It’s convenient (albeit a little strange) to have both types of quotes available for the same purpose, because sometimes it quotes strings with embedded quotes. One example: jQuery selector:

$('input[name="my input"]').val('');

Answer 2

jQuery - JavaScript.

, ', " - - .

Answer 3

'and "can be used interchangeably in JavaScript / jQuery.

It is a little more reliable to use '.

Why? Because it is easier to move JavaScript code between tags scriptand embedded HTML elements, the general syntax of XHTML is to wrap the event code in ""(for example, onclick="alert('foo')"). Using single quotes prevents the need to exit (for example "alert(\"foo\")") and makes it easy to move code from a string to an external script page.
