# console.warn

Writes a warning to the process log. It works like [console.log](/process-functions/console-log), but the line is logged as a warning so it stands out. It doesn't stop the process.

```js
console.warn(...output)
```

## Parameters

| Parameter | Type | Description |
|---|---|---|
| `output` | `any` | One or more values to write. Several values are joined into one line, and objects are written out in a readable form. |

## Examples

```js
function end() {
    if (script.getRecordsProcessed() === 0) {
        console.warn("No records were loaded.");
    }
}
```
