JavaScript (@hint/parser-javascript)

The javascript parser is built on top of ESLint so hints can analyze JavaScript files.

To use it you will have to install it via npm:

npm install @hint/parser-javascript

Note: You can make npm install it as a devDependency using the --save-dev parameter, or to install it globally, you can use the -g parameter. For other options see npm‘s documentation.

And then activate it via the .hintrc configuration file:

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