I generally keep at least one singleton class which is responsible
for storing global properties. I make those properties accessible
with getters and setters so that I can allow changes in those
properties to trigger events. You can't really do that if you use
_global to store your data. Also, there is always a risk in name
space collision if you load in other elements that also use global,
where one or more variables use the same name and are thus
inadvertently shared for different uses. You definitely do not want
to use _global within any classes that you create, as that can cause
entanglement, gives you no private protection, and does not properly
contain your code into a well-defined unit with a well-defined API.

wondering in which cases I should try to remove those. Is there a
reference that I can read that would educate me on the reasons not
to use
_global and even tell me some workarounds that would allow me to
safely use
_Global if it's necessary. I'm familiar with the use of the Singleton
pattern but feel as if in some cases I might be better with some
_globals.
One case in particular that I'm considering is for some functions
that we
would like to have globally available. Am I better off making them
static
functions of a class (like Math.random() etc)
and having people importing the class or just plopping them as
functions on
the global timeline?
Thanks in advance-
