Add an Array of values as properties of FeatureCollection? (Both have same size and order.)

I’ve got a FeatureCollection of P points and data in an Array with P entries (values/rows) where the order between items in the FC matches the items/rows in the Array.

How can I add the values from the Array as properties of the Features in the FeatureCollection?

My workflow is:

• Images[N]
• N x Sample points(FeatureCollection)[P]
• Array[P,N]
• some array manipulations
• Array [P,W]
• W x Sample points(FeatureCollection)[P] or having W properties

W dimension is small enough and can easily be just a single value that is added to the Feature Collection.

But the P is quite high and iterating over it seems inefficient.

I need this to visualize the results.
