Is there anything similar to Python's numpy.apply_along_axis in Javascript?

Question

I need to translate a Python program into Javascript and I see numpy.apply_along_axis many times but do not know how to do that in Javascript. Please help!

Answer 1

There various ideas of how to create 'multidimensional arrays' in Javascript in this SO question from a few years back

JavaScript multidimensional array

Basically all use nested arrays, the equivalent of Python nested lists.

You have to have some sort of multidimensional array to have a concept of 'axis'. Inevitably some operations will be easier on the first level array than on the deepest level. And there will be speed penalties.

And for a syntax that looks more like Python, consider Coffeescript

Packages like underscore.js and lodash have array/collection iterators and functions that can make operation on arrays easier. There are, for example, zip and flatten functions.
