J (programming Language) - Documentation

Documentation

J's documentation, unlike that of most other programming languages, is organized as a dictionary, with words in J identified as nouns, verbs, adverbs, conjunctions, and so on. Primary words are listed in the vocabulary, in which their respective parts of speech are indicated using markup. Note that verbs have two forms: monadic (arguments only on the right) and dyadic (arguments on the left and on the right). For example, in '-1' the hyphen is a monadic verb, and in '3-2' the hyphen is a dyadic verb. The monadic definition is mostly independent of the dyadic definition, regardless of whether the verb is a primitive verb or a derived verb.
