JavaScript (@hint/parser-javascript)

The javascript parser allows hints to analyze JavaScript files.

This package is installed automatically by webhint:

npm install hint --save-dev

To use it, activate it via the .hintrc configuration file:

    "connector": {...},
    "formatters": [...],
    "hints": {
    "parsers": ["javascript"],

Note: The recommended way of running webhint is as a devDependency of your project.
