Test a property of an array of objects

[borpin]

Thanks everyone, I just wondered if there was an easier way than a function.

I ended up with a function

msg.payload = msg.data.filter(function(data){
    return (data.attributes.device_class == "temperature") && ((data.attributes.last_median_of < 5) || (Date.parse(data.last_updated) + 300000) < Date.now());
}).length > 0;
