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 = { ... }
