What AnatomyOf is built for

AnatomyOf is made by the team that publishes this site.

It shows an example source file with color-coded callouts linked to the exact lines they explain [3]. Hovering a callout highlights its code, and clicking it opens a longer writeup with a Learn more link [3]. Each language has a minimal and a verbose example, and switching between them animates only the lines that change [3]. The same annotated format extends to non-code concepts such as an email and a CI pipeline [3].

Some entries have a third Visual tab with diagrams generated from data and linked to the same annotations [3]. The language list is sorted by TIOBE Index rank, can be switched to A-Z, and has instant search [3]. Code is highlighted with Shiki, the engine VS Code uses [3]. Entries have shareable URLs such as /#/python/verbose [3], and it has light and dark themes and works on phones, where you tap to pin a callout [3].

Pricing and fees

Exercism is 100% free, forever [1]. Insiders access is available via a recurring monthly donation of $10 or more [4], and lifetime Insiders is granted to those who have donated $499 total [4].

Setting it up and daily use

Exercism is primarily built as a CLI-first tool [1] and has an in-browser editor [1]. The facts here give no install command, so check its own pages for how to set it up on your machine.

Learn X in Y Minutes gives a community-driven tour of a next favorite language [2], and its articles are licensed under a CC BY-SA 3.0 license [2]. Its facts here say nothing about local setup.

AnatomyOf runs in any reasonably current desktop or mobile browser [3]. There is nothing to install; to run it locally, use bun install and bun run dev (see Quick start) [3]. Daily, a developer opens the annotated example, hovers a callout to highlight its code and clicks to open a longer writeup [3]. You add a language by writing one LanguageDef TypeScript file under app/src/data/ [3]. AnatomyOf sends one anonymous visit ping per browser session on page load [3].
