Jslint Is Not A Code Quality Tool For 3rd Party Code.
Personally, I’m a big fan of JSLint, but a lot of people take issue with it. This article does (what I feel is) a good job in outlining some qualities of JSLint that some people find unfavorable, things you should be aware of.
I like JSLint primarily for the JavaScript I write myself. I like rules, I like rigidity, I like process. JSLint gives that to me, even if it does inherit some preferences from the author, a man far smarter than I’ll ever be.
One thing I don’t practice, though, is ditching a potential piece of JavaScript because it doesn’t pass the test. I love jQuery.
