LinAlg is a lightweight JavaScript library that implements a wide range of linear‑algebra routines (matrix creation, dot products, transpose, SVD placeholders, etc.) using native `Array`s for speed while prioritizing numerical correctness and full test coverage. It’s aimed at developers who need a low‑level, dimension‑agnostic linear‑algebra toolkit—especially for data visualization, machine‑learning prototypes, or other projects where a pure‑JS solution is preferred over heavier scientific libraries.
