Maybe "Also the creator of JavaScript" is a tongue-in-cheek contention with assuming that JavaScript and "the world's most popular language" are one and the same. Popular itself is a squirrelly word here. Popular can simply refer to as "most used" (by this metric, Xi and Modi would be the world's most popular leaders, since they lead the world's biggest populations), or it could be "most liked" by some other measure (I have no analogous leader to nominate here).
