You-Dont-Know-JS - A book series on JavaScript. @YDKJS on twitter.

This is a series of books diving deep into the core mechanisms of the JavaScript language. The first edition of the series is now complete.Please feel free to contribute to the quality of this content by submitting PR's for improvements to code snippets, explanations, etc. While typo fixes are welcomed, they will likely be caught through normal editing processes, and are thus not necessarily as important for this repository.

mal - mal - Make a Lisp

•    Assembly

Mal is a Clojure inspired Lisp interpreter.Mal is a learning tool. See the make-a-lisp process guide. Each implementation of mal is separated into 11 incremental, self-contained (and testable) steps that demonstrate core concepts of Lisp. The last step is capable of self-hosting (running the mal implementation of mal).

codecombat - Game for learning how to code.

•    CoffeeScript

NOTE: The process for setting up the dev environment has changed. Please refer to the docs for details. It's both a startup and a community project, completely open source under the MIT and Creative Commons licenses. It's the largest open source CoffeeScript project by lines of code, and since it's a game (with really cool tech), it's really fun to hack on. Join us in teaching the world to code! Your contribution will go on to show millions of players how cool programming can be.

ES6-for-humans - A kickstarter guide to writing ES6.

let allows you to create declarations which are bound to any block, called block scoping. Instead of using var, which provides function scope, it is recommended to use block scoped variables (let or const) in ES6. Arrow functions are a short-hand notation for writing functions in ES6. The arrow function definition consists of a parameter list ( ... ), followed by the => marker and a function body. For single-argument functions, the parentheses may be omitted.

ultimate-python - Ultimate Python study guide for newcomers and professionals alike

•    Python

🏆 Serve as a resource for Python newcomers who prefer to learn hands-on. This repository has a collection of standalone modules which can be run in an IDE like PyCharm and in the browser like Replit. Even a plain old terminal will work with the examples. Most lines have carefully crafted comments which guide a reader through what the programs are doing step-by-step. Users are encouraged to modify source code anywhere as long as the main routines are not deleted and run successfully after each change. 🏆 Serve as a pure guide for those who want to revisit core Python concepts. Only builtin libraries are leveraged so that these concepts can be conveyed without the overhead of domain-specific concepts. As such, popular open-source libraries and frameworks (i.e. sqlalchemy, requests, pandas) are not installed. However, reading the source code in these frameworks is inspiring and highly encouraged if your goal is to become a true Pythonista.

webgems - A curated list of resources for devs and designers

•    Vue

codeworld - Educational computer programming environment using Haskell

•    Haskell

CodeWorld is an educational environment using Haskell. It provides a simple mathematical model for geometric figures, animations, and interactive and multi-player games. The web-based programming environment supports this educational mission with a zero-setup editor and compiler, easy sharing and cloud storage of projects, and the ability to run programs right in the web browser using GHCJS.CodeWorld is stable and has been used in schools for years! See the users page for a partial list. We're constantly improving the environment, though. Breaking changes, when necessary, are scheduled to occur between typical (U.S.) K-12 school semesters, to minimize disruption of existing classes.
