Ответы

Мутирующие методы массива - это методы, которые при использовании на массиве изменяют его. Для понимания - есть методы, которые при вызове не меняют исходный массив, а делают его копию, и над ней проводят манипуляции например - filter(), map(), concat().
Рассмотрим пример работы мутирующих методов, таких как push(), pop().
Пример добавления в массив элемента с помощью мутирующего метода:
Пример добавления в массив элемента без изменения исходного:
Пример удаления из массива элемента с помощью мутирующего метода:
Пример удаления из массива элемента без мутации:

js&quot;,&quot;created_at&quot;:&quot;2022-11-18T09:08:47.446Z&quot;,&quot;details&quot;:null,&quot;best_answer_id&quot;:1276,&quot;related_stacks_count&quot;:5},&quot;id&quot;:1276,&quot;state&quot;:&quot;active&quot;,&quot;body&quot;:&quot;Мутирующие методы массива - это методы, которые при использовании на массиве изменяют его. Для понимания - есть методы, которые при вызове не меняют исходный массив, а делают его копию, и над ней проводят манипуляции например - `filter()`, `map()`, `concat()`.\r\n\r\nРассмотрим пример работы мутирующих методов, таких как [push()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/push), [pop()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/pop).\r\n\r\nПример добавления в массив элемента с помощью мутирующего метода:\r\n```js\r\nconst arrNumbers = [34, 26, 356, 12, 9, 5, 10];\r\narrNumbers.push(&#x27;a&#x27;);\r\nconsole.log(arrNumbers);\r\n// -&gt; [34, 26, 356, 12, 9, 5, 10, &#x27;a&#x27;]\r\n```\r\n\r\nПример добавления в массив элемента без изменения исходного:\r\n```js\r\nconst arrNumbers = [34, 26, 356, 12, 9, 5, 10];\r\ncosnt names = [&#x27;Ivan&#x27;, &#x27;Maria&#x27;];\r\nconst result = arrNumbers.concat(names);\r\nconsole.log(arrNumbers);\r\n// -&gt; [34, 26, 356, 12, 9, 5, 10];\r\nconsole.log(result);\r\n// -&gt; [34, 26, 356, 12, 9, 5, 10, &#x27;Ivan&#x27;, &#x27;Maria&#x27;]\r\n```\r\n\r\nПример удаления из массива элемента с помощью мутирующего метода:\r\n```js\r\nconst arrNumbers = [34, 26, 356, 12, 9, 5, 10];\r\narrNumbers.pop();\r\nconsole.log(arrNumbers);\r\n// -&gt; [34, 26, 356, 12, 9, 5]\r\n```\r\n\r\nПример удаления из массива элемента без мутации:\r\n```js\r\nconst arrNumbers = [34, 26, 356, 12, 9, 5, 10];\r\nconst filteredArray = arrNumbers.filter((num) =&gt; num !== 10); \r\nconsole.log(arrNumbers);\r\n// -&gt; [34, 26, 356, 12, 9, 5, 10]\r\nconsole.log(filteredArray);\r\n// -&gt; [34, 26, 356, 12, 9,

Для понимания - есть методы, которые при вызове не меняют исходный массив, а делают его копию, и над ней проводят манипуляции например - `filter()`, `map()`, `concat()`.\r\n\r\nРассмотрим пример работы мутирующих методов, таких как [push()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/push), [pop()](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/pop).\r\n\r\nПример добавления в массив элемента с помощью мутирующего метода:\r\n```js\r\nconst arrNumbers = [34, 26, 356, 12, 9, 5, 10];\r\narrNumbers.push(&apos;a&apos;);\r\nconsole.log(arrNumbers);\r\n// -&gt; [34, 26, 356, 12, 9, 5, 10, &apos;a&apos;]\r\n```\r\n\r\nПример добавления в массив элемента без изменения исходного:\r\n```js\r\nconst arrNumbers = [34, 26, 356, 12, 9, 5, 10];\r\ncosnt names = [&apos;Ivan&apos;, &apos;Maria&apos;];\r\nconst result = arrNumbers.concat(names);\r\nconsole.log(arrNumbers);\r\n// -&gt; [34, 26, 356, 12, 9, 5, 10];\r\nconsole.log(result);\r\n// -&gt; [34, 26, 356, 12, 9, 5, 10, &apos;Ivan&apos;, &apos;Maria&apos;]\r\n```\r\n\r\nПример удаления из массива элемента с помощью мутирующего метода:\r\n```js\r\nconst arrNumbers = [34, 26, 356, 12, 9, 5, 10];\r\narrNumbers.pop();\r\nconsole.log(arrNumbers);\r\n// -&gt; [34, 26, 356, 12, 9, 5]\r\n```\r\n\r\nПример удаления из массива элемента без мутации:\r\n```js\r\nconst arrNumbers = [34, 26, 356, 12, 9, 5, 10];\r\nconst filteredArray = arrNumbers.filter((num) =&gt; num !== 10); \r\nconsole.log(arrNumbers);\r\n// -&gt; [34, 26, 356, 12, 9, 5, 10]\r\nconsole.log(filteredArray);\r\n// -&gt; [34,

Для понимания - есть методы, которые при вызове не меняют исходный массив, а делают его копию, и над ней проводят манипуляции например - <code style="margin-bottom:var(--mantine-spacing-lg)" class="m_dfe9c588 mantine-InlineCodeHighlight-inlineCodeHighlight m_e597c321 mantine-CodeHighlight-codeHighlight m_dfe9c588 mantine-InlineCodeHighlight-inlineCodeHighlight">filter()</code>, <code style="margin-bottom:var(--mantine-spacing-lg)" class="m_dfe9c588 mantine-InlineCodeHighlight-inlineCodeHighlight m_e597c321 mantine-CodeHighlight-codeHighlight m_dfe9c588 mantine-InlineCodeHighlight-inlineCodeHighlight">map()</code>, <code style="margin-bottom:var(--mantine-spacing-lg)" class="m_dfe9c588 mantine-InlineCodeHighlight-inlineCodeHighlight m_e597c321 mantine-CodeHighlight-codeHighlight m_dfe9c588 mantine-InlineCodeHighlight-inlineCodeHighlight">concat()</code>.</p>
