这个烟花效果代码整体实现得很好，我给出以下优化建议： 1. 性能优化： ```javascript // 使用transform替代top/left进行动画 particle.style.transform = `translate(${currentX}px, ${currentY}px)`; // 使用will-change提示浏览器优化 particle.style.willChange = 'transform, opacity'; ``` 2. 内存管理优化： ```javascript // 添加粒子池回收机制 const particlePool = []; function getParticle() { return particlePool.pop() || document.createElement('div'); } // 移除时回收粒子 document.body.removeChild(particle); particlePool.push(particle); ``` 3. 视觉效果增强： ```javascript // 添加随机闪烁效果 const flicker = Math.random() * 0.5 + 0.5; particle.style.boxShadow = `0 0 ${10*flicker}px ${2*flicker}px ${color}`; // 添加重力加速度 const gravity = 0.0001; currentY += gravity * elapsed * elapsed; ``` 需要注意的逻辑点： 1. 粒子数量过多可能导致性能下降，建议设置最大粒子数限制 2. transform动画比top/left性能更好，但要注意浏览器兼容性 3. 粒子池实现需要考虑初始化和重置状态的问题 [2025-05-03 15:21:54 | AI写代码神器 | 280点数解答]
