$(”) vs $(”) in jQuery

by

There is no difference, as seen in the source code, line 30 & line 121:

/* Line 30*/
rsingleTag = /^<(\w+)\s*\/?>(?:<\/\1>)?$/,

/* Line 121 */
// If a single string is passed in and it's a single tag
// just do a createElement and skip the rest
ret = rsingleTag.exec( selector );

The following are equivalent:

  • <a></a>
  • <a />
  • <a>
