The Best way and recommended way of comparing date in typescript is  var today   new Date   getTime    var reqDateVar   new Date somedate  getTime     if today     reqDateVar       NOW   else       Some other time

for completeness  taken from this solution   You could use toDateString   var today   new Date    var isToday    today toDateString      otherDate toDateString       no library dependencies  and looking cleaner than the  setHours    approach shown in a previous answer  imho

function sameDay  d1  d2      return d1 getUTCFullYear      d2 getUTCFullYear    amp  amp           d1 getUTCMonth      d2 getUTCMonth    amp  amp           d1 getUTCDate      d2 getUTCDate       if  sameDay  new Date userString   new Date                 Using the UTC  methods ensures that two equivalent days in different timezones matching the same global day are the same   Not necessary if you re parsing both dates directly  but a good thing to think about
