Comparing two arrays

You can try this as well.

a!localVariables(
  local!arr1:{1,2,4},
  local!arr2:{1,2,3},
  a!forEach(
    items: local!arr1,
    expression:fv!item=local!arr2[fv!index]
  )
)

Comparing two arrays returns a list of booleans. This might be a little better:

a!localVariables(
  local!array1: { 1, 2, 3 },
  local!array2: { 1, 2, 3 },
  not(contains(local!array1 = local!array2, false))
)

Hi,
Adding to Harshit's and Stefan's comments, you can also use Appian's OOTB function 'exact', which will help you, in case you need to compare in a case-sensitive manner.

a!forEach(
  items: merge({ "a", "B", "C" }, { "a", "b", "C" }),
  expression: exact(fv!item[1], fv!item[2])
)

Sure, but why would you want to do that?

Can we use foreach() inside a foreach() ?

{"a","c","b"}={"a","b","c"}

As unreal as it looks, just an equal operator will work.

Did you try a simple foreach() that compares the values on both lists by index? This will get you a list of booleans.
