 Comments increase the overall code footprint, but that's not a problem at all. There are many tools which minify the code before publishing to production server. They remove comments, so they do not appear in the working scripts. So, the comments do not have any negative effects on production at all.

 There exist three most widely used type conversions: to string, to number and to boolean.
