• Removed useless comments, they say the same thing as the statements themselves!
• Only use variables when used more than once

@sovainfo Thanks for PR. What I think is that it will be good to leave detailed code for explanation purpose. I mean at expert level it is easy to understand but on fresher level it's hard to understand code in one line without code comments.

@sovainfo thanks for the PR. My apologies for missing it!

I do like the idea of having best practices followed here. The changes at https://github.com/joomla/Joomla-3.2-Hello-World-Component/pull/9/files#diff-75947db5b8755a95db8e179de97bff6dR13 do seem good to me.

@gunjanpatel what are your thoughts of that change, if accompanying notes are left in place?

@betweenbrain That's good. np. 👍
