Arcade expression for date equals today or earlier

Question

How can I write an arcade expression that would change the symbology of a webmap based on whether or not a date is equal to or before today's date?

Hi, you can do something like this:

var event_time = $feature.eventTime;

var today_date = Today();
var diff = DateDiff(today_date, event_time, 'days');

if(diff > 0){
 return 'before today';
}

else(diff <0)
 return 'today';
