Question

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

The ways I'm talking about are

• <script>....</script>
• <script language="javascript">.....</script>
• <script type="text/javascript">...........</script>

So how do they all do the same thing as the other?

Answer 1

According to the w3c spec , an attribute is required typeand defines the script language, while an attribute language(which does more or less the same) is deprecated in favor type, so you should use the attribute type.
