问题描述
我有2个数组。 arr1将是一个超集，而arr2将是一个子集，并且arr2的大小将始终小于arr1。
我想找出arr1中哪些值不在arr2中。
例如
arr1 = [
"07d65369-78eb-4afb-aba8-710ac146b93f","15d65369-25eb-9u4b-6t7m-820ac145t8w1"
]
arr2 = [
"07d65369-78eb-4afb-aba8-710ac146b93f"
]
预期结果应为[“ 15d65369-25eb-9u4b-6t7m-820ac145t8w1”]
解决方法
也许是这样。
%dw 2.0
output application/json
var arr1 = [
"07d65369-78eb-4afb-aba8-710ac146b93f","15d65369-25eb-9u4b-6t7m-820ac145t8w1","435rt3e-25eb-gh56-6t7m-njhyuiigt6565"
]
var arr2 = [
"07d65369-78eb-4afb-aba8-710ac146b93f","435rt3e-25eb-gh56-6t7m-njhyuiigt6565"
]

arr1 -- arr2
