Parse, compare and bump semantic versions

    Parse & bump version

    Compare two versions

    Comparison honours pre-release precedence per semver 2.0.0 — e.g. 1.0.0-alpha < 1.0.0, and numeric identifiers are compared as numbers (1.2.0 < 1.10.0).

    About

    Work with semantic versions: parse a version into its components, validate it, bump it to the next major/minor/patch/prerelease, and compare two versions. Follows Semantic Versioning 2.0.0, including pre-release and build metadata. Everything runs in your browser; nothing is uploaded.

    2D Fluid Dynamics & Particle Physics Sandbox

    A physics playground with two engines sharing one canvas. The fluid mode runs a real Eulerian Navier-Stokes solver — semi-Lagrangian advection, explicit diffusion, Jacobi pressure projection and vorticity confinement — that you paint with dye and velocity using mouse or touch. The particle mode is a damped Verlet N-body engine with gravity wells, Coulomb attractors and repulsors, spring links, wall restitution and elastic circle collisions. Particle counts adapt to the device (100k target on WebGL2 desktop, 2k-5k on CPU fallback), and every configuration exports as runnable code: a Matter.js world, a PixiJS ticker setup, or a standalone vanilla Canvas engine.

    Algorithm Arena & Data Structure Visualizer

    Interactive arena for algorithms and data structures: eight sorting algorithms racing on one seeded input, six pathfinding algorithms walking generated mazes, and BST, AVL, Red-Black, B-tree, heap and trie operations replayed step by step with rotations highlighted. Every run shows the Big-O table and the phase-highlighted reference implementation in four languages, and compared values can be played as pitch (sonification) through the shared audio engine. Everything runs client-side; inputs never leave the browser.
