The '''J''' programming language combines an ASCII encoding of APL as embodied by [[SHARP APL]] with functional techniques developed by [https://en.wikipedia.org/wiki/John_Backus John Backus] for the [https://en.wikipedia.org/wiki/FP_(programming_language) FP] and [https://en.wikipedia.org/wiki/FL_(programming_language) FL] languages. J is characterized by its use of [[leading axis theory]] as a foundational design principle and its [[tacit programming]] capabilities. [[Function trains]] are a key J feature and were later adopted by [[Dyalog APL]]. J's primitives consist of a single ASCII character possibly followed by one or two periods (<code>.</code>) or colons (<code>:</code>). It is also notable for its use of terms from English grammar to describe the language. For example, [[functions]] are called "verbs" while arrays are called "nouns". | The '''J''' programming language combines an ASCII encoding of APL as embodied by [[SHARP APL]] with functional techniques developed by [https://en.wikipedia.org/wiki/John_Backus John Backus] for the [https://en.wikipedia.org/wiki/FP_(programming_language) FP] and [https://en.wikipedia.org/wiki/FL_(programming_language) FL] languages.
