It is worth learning, but the chances of using it for more than toy scripts are slim. Unless your workplace has already bought into it, you'll find it a hard sell. There are several other functional languages out there with more vibrant communities that have useful libraries.
One selling point, the terseness/simplicity of code, can be a specious one. Beyond the magic of map/flatmap/etc, the things that allow you to achieve terseness in a general sense often require more cryptic constructs as scaffolding.
One developer friend made a comment that summarizes functional languages well in practice: "They're very useful, but try to avoid code that requires your coworkers to know abstract algebra and category theory in order to contribute to a project."
