There's nothing wrong with learning bleeding edge--it's fun! But don't bank on it to provide a job. I'm not a front end dev, so YMMV and etc, but I think it's always good to learn a popular language/framework and then play with the new and fringe stuff. At the very least, you'll have another bit of knowledge to compare things to. At worst you'll have had some fun learning something new.

If you get really good with whatever you're learning, you can just bid on freelance contracts where no language or toolset is specified.
