The pluggable linting utility for JavaScript and related frameworks.

ESLint is a JavaScript linting tool.

It differs from other linters in that every rule is a separate plugin and you can add more during runtime.

User interface

ESLint is a CLI tool and runs directly from a terminal/command prompt. It may be used as a standalone tool or integrated with an automated task runner such as Grunt (through plugins such as eslint-grunt and grunt-eslint). It can also be integrated with majority of modern editors that support JavaScript. For the list of integrations see ESLint site
