Commenting style

[anonymous]

From 1.7rc1:

on: function( types, selector, data, fn, /*INTERNAL*/ one ) {

This type of commenting goes against the code style guidelines (​http://docs.jquery.com/JQuery_Core_Style_Guidelines)

Same goes with

			if ( window.DOMParser ) { // Standard
				tmp = new DOMParser();
				xml = tmp.parseFromString( data , "text/xml" );
			} else { // IE
				xml = new ActiveXObject( "Microsoft.XMLDOM" );
				xml.async = "false";
				xml.loadXML( data );

Although our style guide doesn't explicitly cover comments of this nature, please remember that comment formats may deviate where it's absolutely necessary. Take for example the code you cited, albeit in a simpler form with the other comment format used:

function on(a , b , c //comments){ console.log('hello world'); }

If you paste this into your console, you'll get a syntax error as the comment is being used inline but expects the rest of the line to also be a comment. Contrast this with:

function on(a , b , c /*comments*/){ console.log('hello world'); }

which preserves the comment but doesn't result in any syntax errors because we've implicitly stated where the comment block ends (this is why '' style comments are generally used on either a dedicated line or at the end of a line and the other style of comments can be used anywhere). I hope that clears it up!

That's not my point Addy. I think it should be:

// The third argument c is special
function on(a, b, c) { console.log('hello world'); }

As the style guide says (​http://docs.jquery.com/JQuery_Core_Style_Guidelines#Comments)

Single line comments should always be on their own line

The /* internal */ comment is used for internal arguments in several places. I think we all prefer that because it's easy-to-read and makes sense. I'd be ok with adding this exception to the styleguide.
