- ESLint uses an AST to evaluate patterns in code.
- ESLint is completely pluggable, every single rule is a plugin and you can add more at runtime.
You can install ESLint using npm:
npm install -g eslint
eslint test.js test2.js
Frequently Asked Questions
Why don't you like JSHint???
I'm not giving up JSHint for this!
That's not really a question, but I got it. I'm not trying to convince you that ESLint is better than JSHint. The only thing I know is that ESLint is better than JSHint for what I'm doing. In the off chance you're doing something similar, it might be better for you. Otherwise, keep using JSHint, I'm certainly not going to tell you to stop using it.
What are the plans for ESLint?
Our first goal for ESLint is to hit rule and stability parity with JSHint so that developers can start using ESLint as part of their production toolchain. The master list of JSHint features to be implemented is maintained in this Google Docs spreadsheet. To read about plans beyond parity with JSHint, check out the ESLint Roadmap.
What about ECMAScript 6 support?
At the moment, ES6 support is turned off due to the experimental nature of the support in Esprima. There is basic support for
const, but aside from that, the rest of the features are unsupported. We will re-evaluate ES6 support after v0.5.0.
