I don't see what makes Javascript the worst language in existence? Some of its cruft is being removed (mainly the horrible var scope) with ES6/7. I think some future revision of JS that removes most the cruft (like ; insertion) will be awesome.
I wouldn't call it the worst language in existence by any means, but it does have some things I find extremely irritating - lack of a decent module system, overly verbose at times (like when creating anonymous functions), sneaky silent type conversions that still get me from time to time (sorting a list of integers - oops, lexicographical, not numerical ordering).
Having said that, it also has a lot of cool features and I use it every day. Most of the time, I find it a decent enough experience.
Yes, mandatory semicolons are good, looking forward to it. People are also discovering best practices in JavaScript, which is also good. In lots of regards, however, it will always be inferior to languages that are thought through from the very beginning, and tons of headaches could be saved with just a little more investment in proper environments.
