Does object exist ignoring functionsThe exists() function can tell you whether an object exists at all, or whether an object exists with a certain type, but it can be useful to know whether an object exists as genuine data (and not a function) which can be important when a variable or object is accidently or intentionally given the same name as a function. This function usually returns a logical value as to the existence of the object (ignoring functions) but can also be set to return the non-function type if the object exists.
