Hi, I am new to Node.js too and this got me confused:
What is the difference between
*exports.nyFunc = myfunc;*
and
*module.exports = ...*
thanks,
Alain

BOOM! Thank you...that was exactly what I was looking for. Much
easier on the eyes and keeps everything away from Global
Thanks for everyone who responded so quickly.

Hmmm... maybe something like:
function myfunction(...) {
...
}
function MyDice() {
...
// calling my function
myfuncion()
}
function MyDie() {
...
// calling my function
myfuncion()
}
module.exports = {
MyDice: MyDice,
MyDie: MyDie
}
I don't sure you need to export myfunction, but you can include it
in the about module.exports = { ... }

I'm new to Node.js and finally making some headway before
running into module.exports
I wanted to separate some code out into an external file, so I
created the file and called it probability.js
The problem I ran into was having to define the function
getRandomInt twice to allow it to be called by the Die methods
and by the primary server code. I'm sure this is a scope
issue, but I have not been able to figure out how to resolve
it in the proper way. Ideally, I want the getRandomInt
function defined one time within module.exports, but not part
of Die or Dice objects while still allowing the Die and Dice
methods to call it. Any assistance is appreciated.
module.exports = {
// Returns a random integer between min and max
// Using Math.round() will give you a non-uniform distribution!
getRandomInt: function(min, max) {
return Math.floor(Math.random() * (max - min + 1) + min);
},
Die: function(numSides) {
// constructor;
var sides = numSides;
var lastRoll = -1;
this.roll = function() {
console.log("sides: %d", sides);
lastRoll = getRandomInt(1, sides);
}
this.getLastRoll = function() {
return lastRoll;
}
},
Dice: function() {
var myDie = new Array();
var totalDie = 0;
this.addDie = function(newDie) {
myDie.push(newDie);
totalDie = totalDie + 1;
}
this.roll = function() {
for (i=0; i<totalDie; i++) {
myDie[i].roll();
}
}
this.getTotalRoll = function() {
var total = 0;
console.log("Get Total Roll");
for (i=0; i<totalDie; i++) {
console.log('Dice: %d = %d', i,
myDie[i].getLastRoll());
total = total + myDie[i].getLastRoll();
}
return total;
}
}
};
// Returns a random integer between min and max
// Using Math.round() will give you a non-uniform distribution!
var getRandomInt = function(min, max) {
return Math.floor(Math.random() * (max - min + 1) + min);
}
// Returns a random number between 0 (inclusive) and 1 (exclusive)
var getRandom = function () {
return Math.random();
}
