How to filter items from an array of day values where a day's integer value has to match any timestamp from a second array of event items?

Question

In JSX I am mapping through a number of days that I have calculated in a month:

  {range(daysInMonth).map((i) => (
          <div
            className="day-cell day-cell--in-month"
            key={i}
          >
            {i + 1}
          </div>
        ))}

I then have a array of events coming from an api:

const events = [
{
date: timestamp,
description: "Meeting with friends"
}
//More events//
]

How can I map through the array of events and match the event timestamp to the current timestamp of the date for the daysInMonth that is being mapped and then display the event description?
