This is satire but it's pretty lame and unconvincing satire, so much so that I didn't realize it until about 1/3 of the way in. The funniest thing here is a Go developer complaining about JavaScript's unpredictable behavior.
I'm not going to take the bait and start a flame-war. I will just say that odd quirks don't make either of them a bad language because they each have many other benefits. And that the author shouldn't quit his day job to become a comedian.
The underlying point was to make fun of Javascript. That's an usual activity developers do when bored, so I'm not sure the author was trying to convince anybody. But I do agree, if he was trying to convince anybody, he failed.
