How to use

Every current browser supports this, but it only became Baseline on Apr 16, 2024. Use it as a progressive enhancement, or keep a fallback if you support older devices.

Example

JS
const segmenter = new Intl.Segmenter("en", { granularity: "word" });
const words = [...segmenter.segment("Hello, world! 👋")]
  .filter((s) => s.isWordLike)
  .map((s) => s.segment); // ["Hello", "world"]

Feature detection

JS · check before using
if ("Segmenter" in Intl || ("prototype" in Intl && "Segmenter" in Intl.prototype)) {
  // Intl.Segmenter is available
}
