|descr= Intersects array1 with array2 returning array of unique common elements. Additionally, using the same array for array1 and array2 will simply return array of unique elements. Intersects only 1st dimension of an array.
|descr= Intersects two arrays returning an array of unique common elements, avoiding [[nil]] values.
Using the same array as both parameters will return unique elements of that array.
Intersects only the first dimension of said arrays.

Syntax

Syntax:
array1 arrayIntersect array2
Parameters:
array1: Array
array2: Array
Return Value:
Array

Examples

Example 1:
_arr1 = [1,2,3,4,5,2,3,4]; _arr2 = [4,5,6,1,2,3,5,6]; hint str (_arr1 arrayIntersect _arr2); // [4,5,1,2,3]
Example 2:
_arr = [1,2,3,1,2,3,1,2,3,4,5]; hint str (_arr arrayIntersect _arr); // [1,2,3,4,5]
Example 3:
Remove nils:
hint str ([1,2,nil,3] arrayIntersect [1,2,nil,3]); // [1,2,3]
Example 4:
Also works with array elements which are equal:
hint str ([[1],[2],[3]] arrayIntersect [[2],[3],[4]]); // [[2],[3]]
Example 5:
This command is case-sensitive:
["cAse"] arrayIntersect ["cAse"]; // ["cAse"] ["cAse"] arrayIntersect ["casE"]; // []
