Compare Exercism's exercises and mentoring with AnatomyOf's annotated code examples, and match each to how you learn. Exercism says it is 100% free, forever, and it pairs coding exercises with human mentoring. [^1] [^1] AnatomyOf shows example source files with color-coded callouts that explain each line, so it is a different way to learn syntax: reading rather than solving.

It shows an example source file with color-coded callouts linked to the exact lines they explain. [^2] Hovering a callout highlights its code, and clicking it opens a longer writeup with a Learn more link. [^2] Each language has a minimal and a verbose example, and switching between them animates only the lines that change. [^2] It extends the same annotated format to non-code concepts such as an email and a CI pipeline. [^2] Some entries have a third Visual tab with diagrams generated from data and linked to the same annotations. [^2] The language list is sorted by TIOBE Index rank, can be switched to A-Z, and has instant search. [^2] Entries have shareable links, so you can send a colleague the exact example you mean. [^2] It highlights code with Shiki, the engine VS Code uses. [^2] It has light and dark themes and works on phones, where you tap to pin a callout. [^2] AnatomyOf is free, with no account and no paid tier. [^2] It is open source under the MIT License. [^2] It runs in any reasonably current desktop or mobile browser. [^2] There is nothing to install. [^2] It sends one anonymous visit ping per browser session on page load, and the README says it collects anonymous usage statistics.
