'''BQN''' is an APL-family language designed primarily by [[Marshall Lochbaum]]. Although it maintains the concept of array-driven computing and much of APL's array functionality, BQN discards all [[backwards compatibility|compatibility]] with other array languages and changes many fundamental concepts. It uses the [[based array model]] with dedicated [[array notation]], distinguishes between data types and expression roles to give the language a [[wikipedia:context-free grammar|context-free grammar]] with [[wikipedia:first-class function|first-class function]]s, and uses a new set of [[glyph]]s with different primitive pairings. The language uses the [[leading axis model]] and [[tacit programming]] as core paradigms. Its implementation is largely self-hosted, with an array-based compiler like [[Co-dfns]]. | '''BQN''' is an APL-family language designed primarily by [[Marshall Lochbaum]].

== Implementations == | |||
BQN has several implementations,<ref name="running"/> with all complete ones based on self-hosted sources, which are compiled to bytecode and included as literal arrays or similar in the implementation's source. [https://github.com/dzaima/CBQN CBQN], developed by [[dzaima]] in [[wikipedia:C (programming language)|C]], is the primary implementation with the best performance. A [[wikipedia:JavaScript|JavaScript]] version can be run online. It's slower than CBQN compiled to [[wikipedia:WebAssembly|Wasm]], but easier to connect with browser functionality. | |||
=== dzaima/BQN === | |||
Now largely replaced by CBQN, dzaima/BQN is [[dzaima]]'s independent implementation in Java, based on [[dzaima/APL]]. While dzaima/APL adds significant new functionality and is different from any other APL, dzaima/BQN follows the BQN specification closely and sometimes extends it with [[system function]]s. It has often been the first implementation to support new functionality, particularly syntax such as block headers, and was the fastest implementation before CBQN was created. It introduced the [[wikipedia:bytecode|bytecode]] format now shared with self-hosted BQN, and was used for development and bootstrapping. | |||
