I remember from another video that key/value pairs must be wrapped in double quotes in order for the JSON to be valid. In this challenge, the conditional isn't matching string values, it's matching whether rooms.available or employees.inoffice === true or false. Why is this?

Full Stack JavaScript Techdegree Graduate 19,570 PointsIn JSON files like employees.json ```{ "name": "Aimee", "inoffice": false }
they key always has quotes around it, but the values only has quotes if it's a string. The key inoffice holds a value of JavaScript type boolean, which is false, which is not a JavaScript string.
But if it was
```{
"name": "Aimee",
"inoffice": "false"
}
then the key inoffice would have a value of JavaScript string which contains "false".
So if you compare with a boolean type:
inoffice === false, is using three === for a strict comparison, so inoffice must be of type boolean.
