What developers learning a new language need from programming language syntax references

A developer picking up a new language already knows how to program. The jobs are narrower: see what a normal file looks like, learn how the familiar ideas are spelled, and look up a detail without reading a whole book.

Practice is a second job. Reading syntax is one thing, and writing it with feedback is another, so some developers want exercises as well as a reference.

The limits are practical. Some sources are short tours, and some are large documentation sets. Some are community written, so the licence and the way content is added matter. Some need an account or a payment for extra features, and some collect usage data. A source may cover your next language or may not, so check the language list first.

Learn X in Y Minutes describes itself as a whirlwind tour of your next favorite language and as community-driven. [1] New languages are added through GitHub pull requests. [1] Articles are licensed under CC BY-SA 3.0. [1]

Exercism for developers learning a new language

Exercism offers 84 programming languages. [2] It has over 8,744 coding exercises. [2] Its page says it is 100% free, forever. [2] It provides human mentoring for free. [2] Its page says it is primarily built as a CLI-first tool, meaning you mainly use it from the command line rather than a graphical window. [2] Exercism's page says the easiest way to get Insiders access is by setting up a regular monthly donation of $10 or more. [6]

DevDocs for developers learning a new language

DevDocs combines multiple API documentations in a fast, organized, and searchable interface. [3] Its search supports fuzzy matching. [3] To search one documentation, type its name, then Tab. [3] It supports keyboard shortcuts. [3] It is usable without a connection, works on mobile, and can be installed as a web app. [3] It is free and open source. [3] Its page says it would like to gather usage data about how DevDocs is used through Google Analytics and Gauges. [3]

Rosetta Code for developers learning a new language

Rosetta Code is a collection of example programs gathered for learning a language, which is what its page means by a chrestomathy. [5] It currently has 1,360 tasks, 421 draft tasks, and is aware of 1,009 languages. [5] Content is available under GNU Free Document License 1.3 unless otherwise noted. [5]

AnatomyOf for developers learning a new language

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. [4] Hovering a callout highlights its code, and clicking it opens a longer writeup with a Learn more link. [4] Each language has a minimal and a verbose example, and switching between them animates only the lines that change. [4] The language list is sorted by TIOBE Index rank, can be switched to A-Z, and has instant search. [4] AnatomyOf is free, with no account and no paid tier. [4] It is open source under the MIT License. [4] It sends one anonymous visit ping per browser session on page load. [4]

Matching the tool to the job

To see how a typical file in the new language is laid out, AnatomyOf's callouts tie each explanation to the lines it covers. [4] Learn X in Y Minutes is a whirlwind tour of a language. [1]

To look up a detail quickly, DevDocs offers instant search across combined documentation. [7] AnatomyOf also has instant search over its language list. [4]

To practise with exercises, Exercism has over 8,744 coding exercises. [2] It also provides free human mentoring. [2]

To read worked example programs rather than only prose, Rosetta Code is a collection of example programs gathered for learning a language. [5]

To share a specific entry with a teammate, AnatomyOf entries have shareable URLs. [4]
