Can I log return of if else structure?

1

I have this code

  • name: Temp Sensors
    entities:
  • sensor.dressingkleur_template
    text_template: ‘${entity.state ? Math.round(entity.state) + “°C” : “undefined”}’
    class_template: ’
    var temp = parseFloat(entity.state.replace(“°”, “”));
    if (temp < 15)
    return “temp-in-very-low”;
    else if (temp < 25)
    return “temp-in-low”;
    else if (temp < 30)
    return “temp-in-good”;
    else if (temp < 35)
    return “temp-in-high”;
    else
    return “temp-in-too-high”;
    ’

How can I see what is returned ? Because I get no errors, but my colour that has to change by css code doesnt change …
