Not perfect, but definitely a much better tool for that work (big front-end apps). JS was not meant for that, it's been stretched far from what it was (quickly) designed for.

And sure, when more people join Elm, bad-written libraries or silly paradigms will crop up, but I'm confident it won't be as bad as the JS landscape is today.

Time will tell I guess. -- Now back to stitching those JS libraries to write some code that might work. Bills have to be paid :)
