"If you're sorting a list of names in JavaScript with less than and greater than signs, you might think it works just fine. And it does if you're only dealing with simple ASCII characters. But look what happens when we add accents to the letters. The accented ones get pushed to the end of the array, because we're actually just comparing Unicode code points, rather than sorting alphabetically. The fix is to use the locale compare function. Now the accented characters We can also pass in extra arguments to this function, such as the locale and an options object. For example, ignore punctuation means characters like hyphens and apostrophes are ignored during comparison. But if you're sorting large arrays, calling locale compare on every comparison is slow because it creates a new locale object each time. That's where the collator comes in. You create it once up front, pass in your locale and options, and then just call collator.compare Some of the other options available include setting the sensitivity to make comparisons case or accent insensitive, and the case first property lets you decide how to sort upper and lower case letters. If this helped you out, be sure to smash that like button and follow or subscribe for more web dev and dotnet tips."
