如何使用node.js迭代包含键值的数组

Question

我有两个阵列

test1 = [{"name":"A","age":10},{"name":"B","age":10},{"name":"C","age":10}]
test2 = [{"name":"A","age":10},{"name":"B","age":10},{"name":"D","age":10}]

我需要根据名称迭代数组，并在每个数组中找到不同的元素

我需要像一样的输出

diff_frm_test1 =[{"name":"C","age":10}]
diff_frm_test2 =[{"name":"D","age":10}]

我尝试使用forEach()，但我得到了组合列表。

Answer 1

您可以根据以下名称过滤数组：

test1 .filter(single => single.name === "C")
