Writing multiple functions in AMD javascript module

Question

I am quite new to writing javascript code using AMD. I am stuck at figuring out how to write multiple functions in a file:

define(function(){
  return {
    and: function(a,b){
      return (a&&b);
    }
  };

}

);

I tried writing another function plus in the following way:

define(function(){
  return {
    plus: function(a,b){
      return (a+b);
    }
  };

}

);

But when I use grunt for testing, it is not able to detect the function plus

You should place each module in it's own file. At least requireJS (are you using that?) determines the module name by it's file name (without the .js).

So a file sitting in /modules/A.js will have the module name "modules/A".

If you really want to define multiple modules in one file, you can do it in a more explicit way like this:

define("A", [], function () { return ...whatever... });
define("B", [], function () { return ...whatever... });

Edit:

for defining one module with two functions you can use different patterns. For a singleton (i.e. no "Class") I usually do something like this:

define(function () {
    var myModule = {
        fn1: function () { .... },
        fn2: function () { .... }
    };
    return myModule;
});
