**asdfjkl** is a lightweight Node.js library that detects whether a string of text is likely gibberish. It trains a character‑transition probability model (by default on “The Adventures of Sherlock Holmes”) and then uses that model to score input strings, returning `true` for gibberish and `false` for normal language. The package is aimed at developers who need a simple, language‑agnostic way to filter out meaningless or nonsensical input in applications such as chat moderation, data cleaning, or spam detection.
