This is a collection of data structures and algorithms implemented in JavaScript (mainly), Python, and Rust. The Python and Rust versions are a work in progress, and only exist for the core sorting and searching algorithms. Everything has at least a JavaScript version.

Why write these all from scratch, especially when there are many implementations written across the internet? I did this mainly to gain a deeper understanding of how each works and for practice.
