count(data:Rest<Dynamic>):Void

groupCollapsed(data:Rest<Dynamic>):Void
Creates a new inline group, indenting all following output by another level; unlike group(), this starts with the inline group collapsed, requiring the use of a disclosure button to expand it. To move back out a level, call groupEnd().
info(data:Rest<Dynamic>):Void

log(data:Rest<Dynamic>):Void
For general output of logging information. You may use string substitution and additional arguments with this method.
