Programming and technology learning points to courses, tutorials and practice sites for people learning to code. The listings include university courses, free video series, interactive lessons, documentation and coding challenges. Some entries are full curriculums, and others cover a single language, framework or topic, while a few are community forums where beginners ask questions. Choosing between them comes down to detail: the level they assume, whether they are free or paid, and how recently the material was updated. Quality varies, so look for courses that include practice rather than only video.
