Intl.RelativeTimeFormat Is A Game Changer In JavaScript

Key Takeaways

formatting durations between two dates in JavaScript used to be pretty difficult but the relative time format formatter makes this so much easier all we need to do is give it a Locale for example let's just say that this is going to be the U.S Locale and then we pass it a few different options the style for example if we want it to be a long or short format so now what I can do is I just say console log F dot format and I pass it in a duration which say negative four and we passed it in a unit let's say days and you can see that says four days ago now if I changed my numeric to be always you can see that it's going to say four days ago if I change this to negative one it's going to say one day ago now if I instead set this to Auto you can see that it says yesterday instead of negative one days ago I can also set this to a positive number I could change this to months and you can see it's in 41 months we can also come in here and change the Locale for example we can do Spanish so we can say right here we have Spanish and now it's in Spanish now if you want to learn how to take this to the next level and write code like this which allows you to format any date based on the time it happened to go I'm gonna have a full blog article on that Linked In the description and comments below
