Neither is entirely complete but they are quite capable for pure programming tasks (say, implementing a compiler). dzaima/BQN has good performance while self-hosted is about a thousand times slower.

The file <a href="https://github.com/mlochbaum/BQN/blob/master/docs/bqn.js">docs/bqn.js</a> is zero-dependency Javascript, and can be loaded from HTML or Node.js. It can also be called directly from the command line (using Node): pass a file and <code><span class='Value'>•args</span></code> or <code><span class='Function'>-</span><span class='Value'>e</span></code> to execute all remaining arguments directly and print the results. <a href="https://observablehq.com/@lsh/bqn">This notebook</a> shows how to run it in an Observable notebook.</p> <p>The version of BQN in this repository is implemented mainly in BQN itself—the compiler is entirely self-hosted, while the runtime is built from a small number of starting functions using preprocessed BQN. It completely supports the core language except for block headers and multiple body syntax, and a few cases of structural Under (<code><span class='Modifier2'>⌾</span></code>). The Javascript-based compiler is also slow, taking about 0.05 seconds plus 1 second per kilobyte of source (this is purely due to the slow runtime, as dzaima+reference achieves 1ms/kB with the same compiler once warmed up).</p> |
