> Browser APIs are all over the place and things get broken constantly. Not really. ES5 (2009, but realistically supported in 2012-2013) still works perfectly fine in pretty much all browsers. There's massive churn in JS frameworks absolutely, but that's not a browser thing. There are even languages still being transpiled to ES5. Just because there's a new js package manager twice a year, it doesn't mean you need to use it :)
