<p>I have an array object and an array. Which values ​​in this array match values ​​in the array object require a change of state (such as true). </p> <p><code>arrObj</code> The output should look like this: </p> <pre class="brush:php;toolbar:false;">[ { name: "Test1", status: true }, { name: "Test2", status: false }, { name: "Test3", status: true } ]</pre> <p>Demo: https://stackblitz.com/edit/github-7plax5-mu3l6a?file=src/app/app.component.ts</p> <p> <pre class="snippet-code-js lang-js prettyprint-override"><code>let arrObj = [{ name: "Test1", status: true }, { name: "Test2", status: true }, { name: "Test3", status: true } ] let arr = ["Test1", "Test3"]; for (k of arr) { if (arrObj.name == k) { arrObj.status = true; } } console.log(arrObj);</code></pre> </p>

arrObj.forEach(item => item.status = arr.includes(item.name))

console.log(arrObj);

<script>
let arrObj = [{
    name: "Test1",
    status: false
  },
  {
    name: "Test2",
