Node Modules - exporting a variable versus exporting functions that reference it?

Question

Easiest to explain with code:

##### module.js
var count, incCount, setCount, showCount;
count = 0; 

showCount = function() {
 return console.log(count);
};
incC         


        

Answer 1

Correct me if I am wrong, but numbers are immutable types. When you change the value of count then your reference changes too. So exports.count references to the old count value.
