Creating an empty element with start tag vs. self closing tag

Question

In jQuery, is there any difference between this:

$(\'
\').appendTo(\'body\');

And this:

$(\'
\').appe         


        
      

Answer 1

No. Neither this $("

") nor this $("

") will cause problems.

The proof is so that if we go to jQuery sources we can see that in case of selector with single tag syntax <...> it parses selector with this regular expression:

rsingleTag = /^<(\w+)\s*\/?>(?:<\/\1>)?$/

where only the symbolic part is used for createElement and closing slash can be optional.
