在Angular中，我有这两个包含对象的数组。

  1. 主要对象
  1. [
  2.     {

  79.         "headers": [

  100.         ],

  102.         "destination": "7"
  103.     },
  104. ]

要比较它们，我创建了一个分离的数组，以使它们相似。我尝试使用过滤器和映射，但没有帮助。

我尝试了不同的方法，但没有成功。所以我没有代码片段。需要根据它们之间的差异比较主要对象和第二个对象，然后修改主要对象。

In Angular I have this 2 arrays with objects.

  1. Main Object

  2. second object

    [

For to compare them, I created a seperated array for to make them similiar to each other. Used filter, map but it wasn't helpful.

I have tried in different ways, and nothing worked. So I don't have the snippet for the code.
Need to compare main object and second object, based on the difference between them have to modify main object.

Sure, here's the translated code:

  1. function updateMainObject(mainArray: any[], secondArray: any[]) {
  2.     const updatedMainArray = mainArray.filter((mainItem) => {
  3.         return (
  4.             mainItem &&
  5.             ((mainItem.uniqueId && !secondArray.some((secondItem) => mainItem.uniqueId === secondItem.UniqueId)) ||
  6.                 (mainItem.userId && !secondArray.some((secondItem) => mainItem.userId === secondItem.Id)))
  7.         );
  8.     });
  10.     return updatedMainArray;
  11. }

You can play with it here.

英文:

<!-- begin snippet: js hide: false console: true babel: false -->

<!-- language: lang-js -->

  1. function updateMainObject(mainArray: any[], secondArray: any[]) {
  2.     const updatedMainArray = mainArray.filter((mainItem) =&gt; {
  3.     return (
  4.       mainItem &amp;&amp;
  5.       ((mainItem.uniqueId &amp;&amp; !secondArray.some((secondItem) =&gt; mainItem.uniqueId === secondItem.UniqueId)) ||
  6.       (mainItem.userId &amp;&amp; !secondArray.some((secondItem) =&gt; mainItem.userId === secondItem.Id)))
  7.     );
  8.   });
  10.   return updatedMainArray;
  11. }

<!-- end snippet -->

You can play with it there
