Stop Splitting Strings the Wrong Way: Discover Intl.Segmenter

Intl.Segmenter is a JavaScript Internationalization API that splits text into human-perceived units (words, sentences, or graphemes) using language-specific rules. Unlike the basic split() method, it handles punctuation, multiple spaces, and languages without whitespace correctly. The API offers three granularity levels: grapheme for counting visible characters, word for tokenization with locale awareness, and sentence for text analysis. Examples demonstrate how the same phrase segments differently across English, French, and Japanese, and practical applications include building locale-aware word counters without regex or external libraries.
