I'm really late to the JS party, having just picked it up a month or so ago. node.js and Meteor are my current tools of choice; it's a rather super environment to get stuff done in.
It's nice to see JS get some positive press.
In fact, JavaScript is the one late to the party, having developed some rudimentary tools only recently. There's nothing exciting about redoing old mistakes in a new ecosystem.
Congratulations you've just unlocked the "Top Negative Statement in a Thread" achievement!
Don't say things like that on HN. Say "Wow, amazing! I did not know this is possible in JS! JS is the future, other languages are not needed!"
