Afternoon,
I’m trying to compare two arrays and return from the first array what isn’t matching in the second. For example. I know this should be simple…
array_1=#(“array_1_a”,“array_1_b”,“array_1_c”,“array_1_d”,“array_1_e”)
array_2=#(“array_1_a”,“array_1_b”,“array_1_c”)
for x = 1 to array_1.count do
(
for xx = 1 to array_2.count do
(
if array_1[x] == array_2[xx] then (
)else(
print array_1[x]
)
)
)
The result i want is this.
“array_1_d”
“array_1_e”
Thanks!

i don’t have max around but i can try to write it blind:
fn arrayDifference arr1 arr2 = for item in arr1 where (finditem arr2 item) == 0 collect item
fn arrayIntersection arr1 arr2 = for item in arr1 where (finditem arr2 item) > 0 collect item

The simplest solution is
for element in array_1 do
if (findItem array_2 element == 0) then print element
but for sure not very efficient.
