Formatting Strings in JavaScript: Sorting, Plurals & Lists

The Intl API provides features for handling strings and lists in different languages, including sorting, pluralization, and list formatting. The Intl.Collator feature helps with sorting and comparing strings correctly, taking into account language-specific rules for alphabetical order, case sensitivity, and accents. It can be used to sort arrays of strings and supports options such as localeMatcher, usage, sensitivity, and ignorePunctuation. Intl.Collator is faster and more customizable than the localeCompare method. The Intl.PluralRules feature helps with handling pluralization dynamically, determining the correct plural form based on the language and count. It supports options such as localeMatcher and type, which can be set to "cardinal" for counting objects or "ordinal" for rankings. The Intl.ListFormat feature helps with formatting lists naturally, taking into account language-specific rules for conjunctions and punctuation. It supports options such as style and type, which can be set to "long", "short", or "narrow" and "conjunction", "disjunction", or "unit" respectively. These Intl features can help make JavaScript applications more international-friendly and user-friendly, saving developers a lot of work and effort. By using these features, developers can support multiple languages effortlessly and provide a better user experience.
