blocks|key|1950606|text|作为其他答案的另一种选择，您可以根据normal属性将数组从最高到最低排序，并选择第一个元素：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1950607|data.sort((a,+b)+=>+parseInt(b.normal,+10)+-+parseInt(a.normal,+10));
console.log(data[0]);+//+The+element+with+the+highest+normal+value
console.log(data[0].normal)+//+Or+just+the+highest+normal+value|code-block|syntax|javascript|1950608|entityMap^0|I|6|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|P|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|Q|8|@]|D|@]|E|$]]]|L|$]]

<p>As an alternative way to the other answers, you could sort your array from the highest to the lowest based on the <code>normal</code> property and select the first element:</p>
<pre class="lang-js prettyprint-override"><code>data.sort((a, b) =&gt; parseInt(b.normal, 10) - parseInt(a.normal, 10));
console.log(data[0]); // The element with the highest normal value
console.log(data[0].normal) // Or just the highest normal value
</code></pre>

<p>Just extract all the numeric values from all the objects in the array, concat them to a collective array, and then find out the max.</p>
<pre><code>const data = [

const getMax = (arr) =&gt; {
  const op = arr.reduce((acc, cur) =&gt; {
    const vals = Object.values(cur).map(v =&gt; +v).filter(v =&gt; v);
    return acc.concat(vals);

  return Math.max.apply(null, op);

console.log(getMax(data)); // 28

<p>I have this array to use in a grouped bar chart. I want to get the maximum value out of all the values, which is 28 in this.</p>
