immutable-js
Immutable persistent data collections for Javascript which increase efficiency and simplicity.
On the second point, I would argue that it's a good thing you get to experience different approaches offered by other developers. In my experience, every library, new or old, has at least one or a few good things going for it, so you get to accumulate a lot of knowledge (which would be beneficial to your career). For example, I never would have known what Structural Sharing is had it not been for ImmutableJS - a library another developer introduced to me when we were working together.
