ngn/apl is an APL bytecode compiler and interpreter by Nick Nickolov. Because it is implemented in Javascript, it can be run in Node.js or any modern browser.

ngn/apl supports most primitives, dfns ({ }), nested arrays, complex numbers (1j2), infinities (¯ or ), forks and atops, strand assignment ((a b)c), indexed assignment (a[b]c), user-defined operators ({⍺⍺ ⍵⍵}), but does not support tradfns (RX f Y), non-zero index origin (⎕IO), comparison tolerance (⎕CT), prototypes, modified assignment (x+1), keywords (:If), object-oriented programming, namespaces.
