<p>Now this must seem to be an easy and stupid question to ask but I must know why we use the dollar ($) symbol in Jquery and JavaScript.
I always put a dollar in my scripts but I actuary don't know why.</p>

<p>For an example:</p>

<pre><code>$('#Text').click(function () {
  $('#Text').css('color', 'red')
});
</code></pre>

<p>This just changes the text colour when you click it, but it chose my point</p>
