The `results` object passed into a formatter is an array of [`result`](#the-result-object) objects containing the linting results for individual files. Here's an example output:

Each object in the `results` array is a `result` object. Each `result` object contains the path of the file that was linted and information about linting issues that were encountered. Here are the properties available on each `result` object:

- **filePath**: The absolute path to the file that was linted.

- **messages**: An array of [`message`](#the-message-object) objects. See below for more info about messages.

- **errorCount**: The number of errors for the given file.

- **warningCount**: The number of warnings for the given file.

- **stats**: The optional [`stats`](./stats#-stats-type) object that only exists when the `stats` option is used.

- **source**: The source code for the given file. This property is omitted if this file has no errors/warnings or if the `output` property is present.

- **output**: The source code for the given file with as many fixes applied as possible. This property is omitted if no fix is available.

Each `message` object contains information about the ESLint rule that was triggered by some source code. The properties available on each `message` object are:

- **ruleId**: the ID of the rule that produced the error or warning. If the error or warning was not produced by a rule (for example, if it's a parsing error), this is `null`.

- **severity**: the severity of the failure, `1` for warnings and `2` for errors.

- **message**: the human readable description of the error.

- **line**: the line where the issue is located.

- **column**: the column where the issue is located.

- **nodeType**: (**Deprecated:** This property will be removed in a future version of ESLint.) the type of the node in the [AST](https://github.com/estree/estree/blob/master/es5.md#node-objects) or `null` if the issue isn't related to a particular AST node.

This option adds a series of detailed performance statistics (see [Stats type](../extend/stats#-stats-type)) such as the _parse_-, _fix_- and _lint_-times (time per rule) to [`result`](../extend/custom-formatters#the-result-object) objects that are passed to the formatter (see [Stats CLI usage](../extend/stats#cli-usage)).
