I don't. Where do you draw the line? if (x = y) as well? if ((x = y))? This is
enforcing idioms that JS does not enforce elsewhere. Leave this to the linters.

Again, I disagree and think this should be left to linters. I don't want to
start partially enforcing coding/parenthesis styles in a limited set of
contexts in the language.
