一行代码实现这些复杂功能，JavaScript太强大了！
<p>JavaScript 以其灵活性和强大的表达能力而闻名，分享一些值得使用的 JavaScript 一行代码解决方案，这些代码简洁优雅却能实现复杂的功能。</p><h2>1. 数组操作神器</h2>
<h3>数组去重</h3>
<pre><code>const unique = arr => [...new Set(arr)];
// 示例
const numbers = ;
console.log(unique(numbers)); //
</code></pre>
<h3>数组扁平化</h3>
<pre><code>const flatten = arr => arr.flat(Infinity);
// 示例
const nested = , ]];
console.log(flatten(nested)); //
</code></pre>
<h3>快速生成数字序列</h3>
<pre><code>const range = (start, end) => [...Array(end - start + 1)].map((_, i) => start + i);
// 示例
console.log(range(1, 5)); //
</code></pre>
<h2>2. 字符串处理技巧</h2>
<h3>生成随机字符串</h3>
<pre><code>const randomString = length => Math.random().toString(36).substring(2, length + 2);
// 示例
console.log(randomString(10)); // "a1b2c3d4e5"
</code></pre>
<h3>字符串反转</h3>
<pre><code>const reverse = str => str.split('').reverse().join('');
// 示例
console.log(reverse('hello')); // "olleh"
</code></pre>
<h3>检查回文字符串</h3>
<pre><code>const isPalindrome = str => str === str.split('').reverse().join('');
// 示例
console.log(isPalindrome('radar')); // true
console.log(isPalindrome('hello')); // false
</code></pre>
<h2>3. 对象处理大师</h2>
<h3>深度克隆对象</h3>
<pre><code>const deepClone = obj => JSON.parse(JSON.stringify(obj));
// 示例
const original = { a: 1, b: { c: 2 } };
const clone = deepClone(original);
</code></pre>
<h3>合并多个对象</h3>
