Intl.ListFormat Is A Really Cool JavaScript Feature

Key Takeaways

formatting a simple comma separated list is pretty easy to do in JavaScript but if you want to do anything more complex than that it gets difficult unless you use the internationalization list format all we need to do is pass it into Locale for example the US and then we can pass it in some different options if we just leave these options blank for now what we can do is we can just say console.log F dot format array and you can see right here it says one two and three which is great now if we wanted we could come in here and we could say that the type is going to be disjunction and that's going to use an or instead of an and we can also change the style for example if we want to have it to be a short style where it doesn't list anything you can see it just has the and symbol or we could have a narrow style where it doesn't have any type of and or or we can also come in here and change the actual Locale that we're using for example we can use Spanish and if I just get rid of the style here you can see that now it has a y for the word and in Spanish and if we just pass in undefined as our Locale it'll use the default Locale which in my case is the US
