Cons
Con Highly opinionated
JSLint has a very strict, dogmatic ruleset that cannot be changed or warnings turned off. So much so that rarely any code will pass JSLint tests. It's reasonable to evaluate if all warning are worth changing.

Con Difficult to know which rule is causing which error
Since you can't edit the rules and it's not programmed in a way to display the rule that's being broken, it's difficult to understand which rule has been broken.
Con No way to support ESnext
Con Requires pyv8
Emmet is a Javascript addon, and it requires pyv8 (python-javascript bridge) to run.
