Javascript Date valueOf()

Introduction

The valueOf() method for the Date type doesn't return a string.

It returns the milliseconds of the date.

It works with operators, such as less-than and greater-than.

Consider this example: 

let date1 = new Date(2019, 0, 1); // "January 1, 2019" 
let date2 = new Date(2019, 1, 1); // "February 1, 2019" 

console.log(date1 < date2); // true 
console.log(date1 > date2); // false

The date January 1, 2019, comes before February 1, 2019.

The milliseconds representation of January 1, 2019, is less than that of February 1, 2019.

Return the primitive value of a Date object: 

var d = new Date();
var n = d.valueOf();
console.log(n);/*from  w  ww. j  av a2  s  .co m*/
