What's the difference between these two JS objects?

function Person0(firstName, lastName){ this.firstName = firstName; this.lastName = lastName; }

var Person1 = function(firstName, lastName){ this.firstName = firstName; this.lastName = lastName; }

:point_right: One is a named function and the other is a variable assigned to an anonymous function.

They would work identically when called, but because of hoisting, the first one would be available both before and after where it is defined, but the second one would be available only after where the variable is assigned.
