FastScan is a JavaScript library implementing the Aho-Corasick algorithm for fast multi-pattern text search, commonly used for sensitive/bad word filtering. It works in both Node.js and the browser and supports quick, longest-match, and hit-count search modes.

Use cases

• filter sensitive words from user-generated content
• find all occurrences of a list of keywords in a text
• scan long articles for forbidden terms
• count keyword hits in a document
• match multiple patterns simultaneously in JavaScript

When to choose

• you need to match a large dictionary of words against text in linear time
• you want a pure JavaScript solution usable in browser and Node.js
• you need sensitive-word or badword filtering in a Chinese or multilingual text pipeline

When to avoid

• you need regex-based or fuzzy matching rather than exact dictionary matching
• memory footprint is critical, since large word lists consume hundreds of MB
• you need an actively maintained library with recent releases and a clear repository license
