In this article I am going to list top 10 linter libraries for javascript. Linter makes your code readable and error free. They prettify and inform you about your syntax errors by rightfully pointing at line numbers.

1. ESLint – A pluggable javascript linter

Number one in our list is ESLint. The best part of this library is that most of the common errors are fixed automatically. Not only that, you can easily customize it to work according to your needs.

So, if you are looking for feature rich linter for your javascript IDE, then our recommendation is ESLint.
