Question: could it be possible to accept other TypedArrays?

[ghost]

The most useful one to add seems Float32Array, but maybe any array could be better ?

One current issue is that a Typed Array (8,16,32) will have to be converted to 64 and takes time and extra memory.

Currently only accepts extensions of DoubleArray, from this interface.

Yes we could.

It makes sense indeed if we can to keep the memory footprint as small as possible. This will be justified for large high-resolution GC/MS (or a dataset of 1000 NMR spectra).

There is already the concept of NumberArray (

cheminfo-types/src/core/NumberArray.d.ts

Lines 6 to 16 in 946936b

	export type NumberArray =
	| number[]
	| Int8Array
	| Uint8Array
	| Uint8ClampedArray
	| Int16Array
	| Uint16Array
	| Int32Array
	| Uint32Array
	| Float32Array
	| Float64Array;

)

Some methods of spectra-processing also already accepts the NumberArray: https://github.com/search?q=repo%3Amljs%2Fspectra-processing%20%20NumberArray&type=code

I don't know however if we should go directly to NumberArray, extend DoubleArray (and allow Float32) or add one more numerical array type.

NumberArray seems useful. Using < T = number [ ] | TypedArray > seems less useful.
