I'm getting the date string from sessionStorage and tying to convert into Date object of format MM/DD/YYYY so I can setDate to a datepicker.
HTML
<div id="demo"></div>
<label class="control-label" for="coverageStartDate">
<input
type="text" id="coverageStartDate"
data-ng-model="coverageStartDate"
class="datepick input-small"
title="MM/dd/yyyy"
pattern="MM/DD/YYYY">
<span class="datepick add-on" for="coverageStartDate">
<i class="far fa-calendar-alt"></i>
</span>
</label>
JS
var startDate = "01/27/2020";
var coverageStartDate = new Date(startDate);
document.getElementById("demo").innerHTML = coverageStartDate;
$("#coverageStartDate").datepicker("setDate", coverageStartDate);
