I would like to sum the array values taking in consideration as the first array index all values greather than 0,
as second value I want sum the next key, eg:

[01] 3.68 + [21] 4.79 + [32] 2.23 + [43] 0.54 + [54] 0.08 + [65] 0.00

How can I implement this logic using EC6?
I though initially to create two loop, but is quite expensive in terms of performance

to understand the question.. you want to sum the values? or keys + values? or both? :D
