🎯 面试准备

常见面试题

jsx

// 1. React 生命周期
class LifecycleExample extends Component {
    componentDidMount() {
        // 组件挂载后调用
        console.log('组件已挂载');
    }

// 2. Hook 等价实现
function HookExample() {

// 3. 状态更新原理
function StateUpdateExample() {

    const handleClick = () => {
        // 这里会打印什么？
        console.log('点击前:', count);
        setCount(count + 1);
        console.log('点击后:', count); // 仍然是旧值

            return prevCount + 1;
        });
    };

编程挑战

jsx
