There are lots of great languages I'd love to use, but if you want to target those common frontend platforms, your choice quickly becomes limited.
Libraries like Re-Frame[0] and Reagent[1], as well as build tools like figwheel[2] or shadow-cljs[3] are the best frontend web development tools I have ever used, and I've used Javascript, Typescript, and Purescript professionally with Angular, AngularJS, React, a big 'ol jQuery glob, and Halogen.
