An example of creating a package

var call_counter = require('./call_counter');
function multiply(x, y){
 call_counter();
 return x * y;
}
function divide(x, y){
 call_counter();
 return x / y;
}
function fibo(count) {
 call_counter();
 return private_fibo(count)
}
function private_fibo(count, counter, first, second) {
 if (count == 0) return 0;
 if (counter == undefined) {
 counter = 1
 first = 1;
 second = 2;
 }
 result = first + second;
 if (counter == count) return result;
 private_fibo(count, ++counter, second, result)
 return result;
}
module.exports = {
 multiplication: multiply,
 division: divide,
 fibonacci : fibo
}
