Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.

Yes. If it's not possible then Espruino won't actively 'compact' the variables to make them fit (yet). Typed Arrays will just silently fall back to being fragmented, but Native code will fail.
The solution is to allocate your big arrays/native code at the start of your program and keep them allocated - which is good practice anyway.
