The only people saying "WTF" about Javascript are people who haven't taken the time to learn how to use it effectively. There are "WTF" things about every language, not just Javascript.
Noobs are going to find the footguns in any language. Every language can be misused. I've been using Javascript over 20 years and have never thought it was any worse than any other language. Yes, it's dynamic, and yes, you can do stupid things with that dynamism, but for someone who actually knows how to use it, it's quite easy to work with.
I recently started using Lua and I'm not impressed at all. It's just another language, it's really up to the programmer what can be done with it, just like Javascript.
