I have seen two different ways to declare variables within functions. How do they differ? Thank you.
Namespace.Class = function() {
// first way. use "var".
var variable1 = 'value';
// second way. use "namespace".
Namespace.Class.variable2 = 'value';
};
var
declares a local variable, meaning it's only visible from within the function, while the second way is for declaring a member of the object, which will be visible from everywhere.
