Some quick code snippets for tutorial on working with the JavaScript date object.

date_object_snippets.js

//iterate date
var myDate = new Date();
var dateInMS = myDate.getTime();
// day in milliseconds = 1000 (milliseconds in a second) * 60 (seconds in a minute) * 60 (minutes in an hour) * 24 (hours in a day) = 86400000 (millseconds in a day)
// 	the getTime() method gets the time in milliseconds since January 1, 1970.
var tomorrow = new Date(datInMS + 86400000);

console.log(myDate);
console.log(tomorrow);

// VM1911:3 Tue Nov 06 2018 14:35:25 GMT+0200 (Israel Standard Time)
// VM1911:4 Wed Nov 07 2018 14:35:25 GMT+0200 (Israel Standard Time)






//Elapsed time:

var start = new Date();
doSomething();
var end = new Date();

var elapsed = end.getTime() - start.getTime();
console.log(elapsed);

function doSomething() {
  for(var i = 0; i < 100000; i++){
    
  }
}





//Iterate over a weeks worth of dates:

var now = new Date();

var newDate = now;

for(var i = 0; i < 7; i++){
  
  console.log(newDate.toUTCString());
  newDate = new Date(newDate.getTime() + 86400000);
  
}
