As cheeze mentioned, it's good for the browser end. Also, if you use a decent IDE to write your code, they often look at that so it knows what type of errors to feed back to you. For example, that signifies HTML5, so then your IDE can let you know which things no longer work with HTML5, for example.

It's not compulsory but it is recommended, it helps when coding, as your code editor might recognize some possible erros.
