Javascript has a Much larger user community. You get much different behavior and discussion when the community's enormous, it's one of the most used computer languages anywhere, and it's available on almost every device with no additional software. Partial example, StackOverflow question counts (measure of community volume and topic need). 2,529,945 questions on JS. [1] Perl? 68,116. [2] (as of 4/30 when linked)
Possible effects: People that must use Javascript, but don't want to (only choice, only framework). People that use Javascript because it's hyped or hot, not because of personal interest. Larger volume of talk, so more opportunities for griping. Much larger perception of griping (blogs, HN links, news. You almost have to work to find the Perl griping locations). The talk tends to more work issues (stuck on project, annoyed at issue), and not discussing a language you write with because you enjoy the features.
