Web Game Dev is a work-in-progress collection of resources, a guide and a newsletter about building games in JavaScript. It covers techniques and tools for 2D and 3D games and visual experiences, including WebGL, Three.js and React. The site states that it currently contains many placeholders and unredacted content.
CS50 is Harvard University's introduction to computer science and programming, intended for students with or without prior experience. It covers computational thinking, abstraction, algorithms and data structures, and programming in C, then Python, and later SQL, HTML, CSS and JavaScript, ending with a final project. The material is available free online through OpenCourseWare over eleven weeks.
A guide to self-study computer science. It recommends nine subjects in a rough order and suggests a textbook or video lecture series for each, with about 100-200 hours of study per topic. It was extensively updated in May 2020 and has volunteer translations.
