<p>whats does the <code>===</code> mean when working with jquery/javascript? and whats the difference between <code>===</code> and <code>==</code>?</p>

<p>like i got this code </p>

<pre><code>if ($this.val() != '' || ignore_empty === true) {
        var result = validateForm($this);

        if (result != 'skip') {
            if (validateForm($this)) {
                $input_container.removeClass('error').addClass('success');
            }
            else {
                $input_container.removeClass('success').addClass('error');
            }
        }
    }
</code></pre>

<p>and there is the <code>===</code></p>

<p>i just want to understand what it does and whats the difference.
thanks</p>
