token‑types is a lightweight JavaScript library that defines binary “tokens” for reading and writing primitive numeric and string values from a Uint8Array/Node Buffer. It’s mainly intended for developers building parsers or tokenizers (e.g., with the accompanying **strtok3** library) who need a simple, type‑safe way to handle big‑ and little‑endian integers, floating‑point numbers and encoded strings in binary files or network messages.
