Sample Javascript module boilerplate

myfunc.js

(function (root, name, factory) {
    'use strict';

    if (typeof define === 'function' && define.amd) {
        define(factory);
    } else if (typeof exports === 'object') {
        module.exports = factory;
    } else {
        root[name] = factory();
    }
})(this, 'myFunc', function () {
    'use strict';

    var myFunc = function () {};

    return myFunc;
});
