Regular expressions with grouping shouldn't be used in String.split()

GoogleCodeExporter commented 8 years ago

DocComment.js has the following line:

  .split(/(^|[\r\n])\s*@/)

It should be replaced by:

  .split(/(?:^|[\r\n])\s*@/)

Without the unnecessary grouping this operation will execute marginally
faster. What's more important for me: Perl's JavaScript 1.11 module (which
I am using to run JSDoc Toolkit instead of Rhino) crashes with that
grouping for some reason. So it would be nice if that simple change could
be taken over in a future JSDoc Toolkit release.

Another line with the same issue in SymbolSet.js:

  var assumedName = borrowed.name.split(/([#.-])/).pop();

Should be:

  var assumedName = borrowed.name.split(/[#.-]/).pop();
