Interesting ... so I started guessing and searching a bit, guided by the
idea that the guy is more experienced with JavaScript than with
Smalltalk. What I found: In JavaScript there is an (incredibly
beautiful) unary plus operator performing a Number cast on the object
following. Being not shure that the value returned from the
configuration call would be an Integer, he or she tried to cast it using
the same unary operator, which did not work out of the box in Pharo ;)
but could be fixed with a 0 as receiver. So I guess / think the
intention behind was totally different compared to what it looks like
for us. It's not very important here, but in general, guessing the
effective intention behind some weird code you have to fix - that's the
really hard part, but might save you a lot of time!

Hi
when cleaning a system sometimes you find some coding pearls.
And I want to share one I found.
currentSlide := 0 + self configuration slideInTemplateForDeckJS.
