RangeError: Maximum call stack size exceeded (native stack depth) when trying to find ratio using Math.max and large array


I have a large numerical array (results of an audio file’s signal which I return to my react native app from a python backend.

And the array looks like this

[1098, 522, 597, 325, 201, 16, ...................... 75, 447, 253, 58, 273]

size of the array is around 535754

I have this code which I use to find raio

peaks = audio_signal_array
const ratio = Math.max(...peaks) / 100
// ratio = 1.1 (example result)
const normalized = peaks.map(point => Math.round(point / ratio))
// normalized = [0, 0, 2, 5, 18, 50, 100, 18] (example result)

Everytime I run this code it throws me the error

error [RangeError: Maximum call stack size exceeded (native stack

So it would be great if anyone can help me to either fix this code from the javascript side or help me convert this code to python so I can return the ratio and the normalized array to the react native app



peaks.reduce((a, b) => Math.max(a, b))

instead of


On the python side, you can simply do

ratio = max(peaks) / 100

See also https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/max:

…spread (…) and apply will either fail or return the wrong result if the array has too many elements, because they try to pass the array elements as function parameters.
