<pre class="snippet-code-js lang-js prettyprint-override"><code>let x = [

<p>what you are looking for is to filter array <code>x</code>, and check if its values is included in array <code>y</code></p>
<pre><code>const x = [
  { value: 0, text: &quot;hello world&quot; },
  { value: 1, text: &quot;how are you?&quot; },

const y = [2, 4];

const result = x.filter((item) =&gt; y.includes(item.value));

console.log(result);

blocks|key|4060876|text|另一种使用.reduce的方法|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|4060877|​|4060878|const+data+=+[

<p>Another way uses <code>.reduce</code>:</p>
<p><div class="snippet" data-lang="js" data-hide="false" data-console="true" data-babel="false">
<div class="snippet-code">
<pre class="snippet-code-js lang-js prettyprint-override"><code>const data = [
   {value: 0, text: "hello world"}, 
   {value: 1, text: "how are you?"}, 
   {value: 2, text: "no problem"},
   {value: 3, text: "anything else?"},
   {value: 4, text: "other dummy text"}
];

function selectValuesFrom(xs, ys) {
  return ys.reduce( // fold ys into a new array
    (a, y) =&gt; {
      // try to find an "x" by the given "y" value
      const r = xs.find(x =&gt; x.value === y);
      // if there is an "x", add it to the new array, otherwise
      // skip it
      return r ? a.concat(r) : a;
    },
    []
  );
}

console.log(selectValuesFrom(data, [2, 4]));
console.log(selectValuesFrom(data, [3, 1, 5]));</code></pre>
</div>
</div>

<p>I have this fixed array:</p>
<pre><code>x = [
   {value: 0, text: &quot;hello world&quot;}, 
   {value: 1, text: &quot;how are you?&quot;}, 
   {value: 2, text: &quot;no problem&quot;}
   {value: 3, text: &quot;anything else?&quot;}
   {value: 4, text: &quot;other dummy text&quot;}
]
</code></pre>
<p>and another dynamic array:</p>
<pre><code>y = [2, 4]
</code></pre>
<p>I would like to filter the array &quot;x&quot; based on the values from array &quot;y&quot;</p>
<p>the expected result should be:</p>
<pre><code>x = [
   {value: 2, text: &quot;no problem&quot;},
   {value: 4, text: &quot;other dummy text&quot;}
]
</code></pre>
<p>How could I do this?</p>
<p>Thanks</p>
