What is difference between $('abc') and $("abc") in jQuery?

Question

What is the difference between $('.abc') and $(".abc") in jQuery?

Example:

var main = function() {
 $('.btn').click(function(event) {
   $('.container').hide();
 });
};

vs

var main = function() {
 $(".btn").click(function(event) {
   $(".container").hide();
 });
};

Both of the code snippets work well. So what is different?

Single and double quotes have nothing to do with jQuery, it's an element of JavaScript. But there is no difference in JS. — Kulvar, Jun 14 '16 at 08:07

They are exactly the same. JavaScript strings can be delimited by either single or double quotes.

I just updated my question. Both of code are correct ? – Don Lee Jun 14 '16 at 07:59
@Don Indeed, there is no difference between the two snippets you had. – Chris Jester-Young Jun 14 '16 at 13:25

No difference; they both are missing a class or ID selector.

Unlike some other languages, JavaScript makes no distinction between single-quoted strings and double-quoted strings; so both will works fine. – Darian Jun 14 '16 at 08:19

In jQuery, there isn't any difference between single or double quotes.

Thanks @Mr Ob. I got it. – Don Lee Jun 15 '16 at 03:44
There is one difference... They are delimited by different characters. `'a'+'b'` means something different than `"a'+'b"` – Paul Jun 23 '16 at 17:39
