Put double quotes around the JS string.
```
echo "<script>console.log(\"photo: ".$sql."\");</script>";
``` | Your javascript console is wrapped in `'` quotes, and your `'$username'` value is also using these single quotes so this is causing a problem.
Therefore; if you want to export this SQL string to your console, you need to escape these single quotes or to use alternative quotes in your javascript.

This uses what is called an **anonymous function**. Like you said, it has no name. It is passed as an argument to `thing.method()`. `thing.method()`'s function body would use this function such as:
