Does it have to be the most popular runtime to counter the "no one really likes JavaScript, we just use it because we have to" claim? As the grandparent said, no one has to use Node, but people do; a lot of them.
I find this topic to be intellectually insulting. You know that JavaScript has its (tens of thousands of) fans. Why tell yourself otherwise? Is your hatred of it so overwhelming that you're not even ready to admit to yourself that others disagree with you?
