Javascript display the "day" instead of the "number"

Question

I have this javascript that will determine the day of the week:

<script>
 function myFunction() {
   var d = new Date();
   var n = d.getDay()
   document.getElementById("demo").innerHTML = n;
 }
</script>

<p id="demo"></p>

Running this code, it'll display 4. Is there anyway I can convert this to an actual string/word like thursday?

you should use an array

 var days = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];
 var day = days[ now.getDay() ];

No, no ,no ,no. Just use the standard javascript Date class. No need for arrays or an extra library. See my answer: https://stackoverflow.com/a/50293232/760777 – RWC May 11 '18 at 13:40

You can use that number as an index to an array of actual day names:

var days = ['sun', 'mon', 'tue', 'wed', 'thu', 'fri', 'sat'];
var date = new Date();
var day = days[date.getDay()];
