check the following simple solution for two date comparison

let d = new Date();
var g1 = new Date(d.getFullYear(), d.getMonth(), d.getDate());
// (YYYY, MM, DD) 
var g2 = new Date(2021, 08, 03);
if (g1.getTime() < g2.getTime())
    document.write("g1 is lesser than g2");
else if (g1.getTime() > g2.getTime())
    document.write("g1 is greater than g2");
else
    document.write("both are equal");
