Question

What is the difference in various ways of defining a script?

The ways I am talking about is this

1. <script>....</script>
2. <script language="javascript">.....</script>
3. <script type="text/javascript">...........</script>

Since, they all do same things, what is different?

Answer 1

According to w3c spec, type attribute is required, and determines script language, whereas language attribute (which does more or less the same) is deprecated in favor of type, so you should use type attribute.
