agreed, and actually one of the best case I've seen in a while for
Array#reduce.
Can I write this as it should be for those who'll read one day later on and
making it also static ?
"mixin" in Object || Object.defineProperty(Object, "mixin", {
value: function mixin(target, source) {
return Object.getOwnPropertyNames(source).reduce(function (target,
name) {
return Object.defineProperty(
target, name, Object.getOwnPropertyDescriptor(source, name)
);
}, target);
}
});
also thinking about try/catch to avoid mixin overwrite ... I believe it's
OK if that throws an error but then it should throw regardless if the
target object had already that property defined ?
