I need a little explanation about the creation of a variable. There is code that creates an object (s_ea) a).  So everything is s_ea.blahblahblah. In the documentation they reinitialize the object before changing any new parameters.

var s_ea = s_gi(s_account);

My question is why use "var" in front of the object name since it already exists? The issue I'm facing is I'm trying to reinitialize the object from a function but using "var" makes it a local variable. If reitializing the variable does need to use "var"  then how  would I do this in a function?
