Sometimes you need to iterate through all the keys within an object. You can use a <dfn>for...in</dfn> loop to do this. The for...in loop looks like:
Manchmal musst du alle Schlüssel innerhalb eines Objekts durchlaufen. Du kannst dazu eine <dfn>for...in</dfn>-Schleife verwenden. Die for...in-Schleife sieht wie folgt aus:

We've defined a function `countOnline` which accepts one argument, `allUsers`. Use a <dfn>for...in</dfn> statement inside this function to loop through the `allUsers` object and return the number of users whose `online` property is set to `true`. An example of an object which could be passed to `countOnline` is shown below. Each user will have an `online` property set to either `true` or `false`.
Wir haben eine Funktion `countOnline` definiert, die ein Argument (ein Nutzer-Objekt) `allUsers` akzeptiert. Use a <dfn>for...in</dfn> statement inside this function to loop through the `allUsers` object and return the number of users whose `online` property is set to `true`. Ein Beispiel für ein Objekt, das an `countOnline` übergeben werden könnte, ist unten abgebildet. Jeder Nutzer wird eine `online`-Eigenschaft mit entweder einem `true` oder `false`-Wert besitzen.
