Just a quick question - does the .sort method in JavaScript automatically sort items in an array using ASCII order? I've been looking at examples, but have yet to find a definitive answer. Are there any alternative methods for alphabetically sorting an array that you would recommend?
Thanks so much in advance!
Absolutely! When you refer to the .sort() method on MDN, it clearly explains what happens when the compare function parameter is left out:
This specifies a function that determines the sorting sequence. If not provided, the array will be sorted based on the Unicode code point value of each character, as per the string conversion of each element.
Given that Unicode includes ASCII, it indeed sorts the elements in ASCII order.
Unless you are comparing "ASCII" to "Kleenex" (as with facial tissue), JavaScript does not operate solely on ASCII characters. Strings in JavaScript consist of UTF-16 code units, each representing one or two Unicode codepoints. This concept also applies to Java, .NET, HTML, XML, and more.
A lexicographic sorting may not be the most practical choice for organizing human-readable text. If you are looking to sort alphabetically, consider utilizing a specific language's writing system's alphabet by using localeCompare in conjunction with sort.
