Google’s client-oriented language, the one beneath Flutter. Unlike JavaScript it has a sound type system with null safety, and compiles both to native machine code and to JavaScript.

https://dart.dev/

Elixir

2026-09-18T00:00:00Z

A functional language on the Erlang VM, strong in scalability. Unlike Erlang it has a Ruby-like syntax and a macro system, while inheriting fault tolerance (OTP) unchanged.

https://elixir-lang.org/

Go

2026-09-18T00:00:00Z

The official site of Google’s simple, fast-compiling language, strong in concurrency. Unlike Java or C++ it is deliberately small: few keywords, one formatter (gofmt), builds in seconds.

https://golang.org/

Haskell

2026-09-18T00:00:00Z

A purely functional, statically typed programming language with lazy evaluation. Unlike most functional languages it is pure: side effects are kept apart in the type system (IO).

https://www.haskell.org/

Julia

2026-09-18T00:00:00Z

A high-performance open-source language for scientific computing. Unlike Python it JIT-compiles to near-C speed, aiming to remove the “two-language problem” of prototyping in Python and rewriting hot code in C.

https://julialang.org/

Julia.jl

2026-09-18T00:00:00Z

A comprehensive list organising Julia packages and resources by topic. Unlike a package search, it hand-classifies packages by scientific field; some sections may be dated.

A language and environment designed for statistics and data analysis, with tens of thousands of packages on CRAN. Unlike Python, new statistical methods usually appear here first, and it has graphics tools such as ggplot2.

https://www.r-project.org/

Ruby

2026-09-18T00:00:00Z

A multi-paradigm language foregrounding readability and developer happiness — the language of Rails. Unlike Python, everything is an object and its flexible syntax lends itself to DSLs.

https://www.ruby-lang.org/en/

Swift

2026-09-18T00:00:00Z

Apple’s safe, fast-compiled language, developed primarily for iOS and also running on Linux and servers. Unlike Objective-C it has a safe memory model built around optionals and a modern syntax.

https://www.swift.org/

CIS 194 Haskell

2026-08-21T20:53:20Z

The University of Pennsylvania’s Haskell course, with lecture notes and assignments public. The difference from a book is the homework — and since Haskell is learned by writing rather than reading, that difference matters.

https://www.seas.upenn.edu/~cis1940/spring13/lectures.html

Learn You a Haskell

2026-08-21T20:53:20Z

The community-maintained online edition of the best-known Haskell introduction. Against the academic Haskell texts the difference is tone: it gets to monads through drawings and incremental examples rather than category theory.

https://learnyouahaskell.github.io/chapters.html

LearnByExample

2026-08-21T20:53:20Z

Teaches Python, SQL and R through runnable examples, opening each concept with one small piece of code. Against documentation the order is reversed — working example first, explanation after — which also makes it a fast syntax refresher.

https://www.learnbyexample.org/

RubyGems Guides

2026-08-21T20:53:20Z

The official guide to how RubyGems works and how to publish your own gem. Against the API reference it also explains the decisions — version numbering, dependency resolution, publishing policy.

https://guides.rubygems.org/

JS Exercises

https://jsexercises.com/

Eloquent JavaScript

2026-08-19T23:33:25Z

A free online classic that builds programming thinking rather than teaching syntax, with exercises runnable inside the book itself.

https://eloquentjavascript.net/

A Byte of Python

2026-08-17T20:53:20Z

https://python.swaroopch.com

Awesome Compilers

2026-08-17T20:53:20Z

A collection of compiler, interpreter and runtime resources, with books, courses and open-source compilers listed separately. Unlike a single textbook, it sets theory, real compiler source and runtime design side by side.

https://aalhour.com/awesome-compilers/

Crafting Interpreters

2026-08-17T20:53:20Z

A free book that has you write a language twice — a tree-walking interpreter in Java, then a bytecode VM in C. Unlike theoretical compiler textbooks it makes you write every line; one of the clearest treatments in the field.
