An APL interpreter written Nick Nickolov in JavaScript, making it run in a under Node.js or in 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 (∇R←X f Y), non-zero index origin (⎕IO), comparison tolerance (⎕CT), prototypes, modified assignment (x+←1), keywords (:If), object-oriented programming, namespaces.
