Collation is used for sorting a set of strings and searching within a set of strings. It is parameterized by locale and aware of Unicode. Let’s take comparison and sorting features,
Comparison:
1 2 3 4 5 | var list = [ "ä", "a", "z" ]; // In German, "ä" sorts with "a" Whereas in Swedish, "ä" sorts after "z" var l10nDE = new Intl.Collator("de"); var l10nSV = new Intl.Collator("sv"); console.log(l10nDE.compare("ä", "z") === -1); // true console.log(l10nSV.compare("ä", "z") === +1); // true |
Sorting:
1 2 3 4 5 | var list = [ "ä", "a", "z" ]; // In German, "ä" sorts with "a" Whereas in Swedish, "ä" sorts after "z" var l10nDE = new Intl.Collator("de"); var l10nSV = new Intl.Collator("sv"); console.log(list.sort(l10nDE.compare)) // [ "a", "ä", "z" ] console.log(list.sort(l10nSV.compare)) // [ "a", "z", "ä" ] |
