JavaScript §1 to §4 are a family of sublanguages, designed for the textbook Structure and Interpretation of Computer Programs, JavaScript Adaptation (SICP JS) and supported by the Source Academy system. The sublanguages are called JavaScript §1, JavaScript §2, JavaScript §3 and JavaScript §4, corresponding to the respective chapters 1, 2, 3 and 4 of the textbook. Each previous sublanguage is a sublanguage of the next, and all of them are sublanguages of full JavaScript. (Chapter 5 does not require any features beyond JavaScript §4.) This webpage contains the description of these JavaScript sublanguages and the libraries they come with.
