In my 35 years of professional programming, getting good at dozens of languages, I've only run across 2 I've actively disliked. Javascript is one of them (tcl was the other). JS is a crap language that IMHO can't be fixed. If they ever add an honest garbage collector to the base language then most programs will delete themselves upon execution.
Lol. And the garbage collector would then send out an email to every web designer who says "I know how to code in Java" when they mean Javascript and clean up that confusion once and for all.
I've been forcing myself to get good at writing JS lately (if only because Node looks like it'll make all my other skills irrelevant in the web development market). It.. just.. feels.. wrong. Nothing in the language lends itself to building architectured solutions. Maybe the testing tools have caught up with other languages now, but you're still testing ugly code.
Javascript is the smallpox of coding languages. Maybe once it's finally eradicated Brendan Eich will only be remembered for this, the equally damaging Rust language and attempting to remove the marriage rights of same-sex couples in California. Hey, did I just politicise Javascript there? Flame on.
