Hey there! I'm diving into the world of JavaScript and have a question that might be beginner level.
So, here's my code snippet:
<script>
var curdate = new Date();
document.write(curdate.setFullYear(1989, 07, 26));
</script>
Instead of displaying the date in a normal format, I'm getting a number like: 620154050573. Even when I tried converting it to a string before displaying, it didn't change. Can someone help me understand why this is happening?
Thanks!
When you use the setFullYear function, the returned value is a Number, not a Date.
var current = new Date();
current.setFullYear(1990, 10, 15)
document.write(current);
It's important to note that adding a prefix of 0 before a number in JavaScript signifies that the number should be treated as octal.
To update the full year of a date object, simply use the setFullYear() method and then display the updated date. For example:
myDate.setFullYear(1999, 11, 31);
console.log(myDate);
When using the setFullYear method, it will return a value that represents the number of milliseconds between the updated date object and midnight on January 1, 1970.
Return Value: A Number, which indicates the difference in milliseconds between the specified date object and Jan 1, 1970
You can find more information about the setFullYear method in the official documentation: http://www.w3schools.com/jsref/jsref_setfullyear.asp
JavaScript Date objects in JavaScript are structured around a time value that represents the number of milliseconds since January 1, 1970 UTC.
To format a Date object, you can utilize one of the various Date object methods available. Check out the MDN Data.prototype documentation for more information.
In the example provided below, I used the toUTCString method, but make sure to explore the link above to discover the method that suits your needs best.
<script>
var currentDate = new Date();
currentDate.setFullYear(1989, 07, 26)
document.write(currentDate.toUTCString());
</script>
