Mixing in such concepts in new is therefore a must - it's not optional any more. When I designed the Mages language I also baked in some powerful functional concepts. Of course, the is not revolutionary, however, I think that scripting is far too important to leave it to languages that come with many constraints due to their history and nature / purpose. Mages is lightweight and fast.
So what do I think about Ramda.js? Well, I think it's a step in the right direction and the creators did a lot of things right. If Mages can use some of the cool stuff they introduced it would be a pleasure for anyone to use. I like the immutable arrays and the object views. The currying aspects and parameter ordering is superb. At least for Node.js projects Ramda.js will be one of my default requires.
