16-16: Whitespace cleanup looks good.The removal of extra whitespace between the assignment operator and opening brace improves code formatting consistency.

Resource leak in page navigation pattern.
When navigateToNewPage() is called, a new ResourceManager instance is created without disposing the previous one, causing resource leaks. Additionally, the function and manager variable are defined but never used.
Apply the following changes to fix the navigation pattern:
// 创建实例但从不销毁
let manager: ResourceManager | null = new ResourceManager();
// 模拟单页应用路由变化，但没有清理旧的资源管理器
function navigateToNewPage() {
// 创建新的管理器，但没有清理旧的
- manager = new ResourceManager(); // 旧的manager实例仍然存在，但已经无法访问
+ if (manager) {
+ manager.dispose();
+ }
+ manager = new ResourceManager();
}If these functions are for testing only and not meant to be used, consider adding a comment explaining their purpose or removing them.

Memory leak in ResourceManager implementation.
This class has several critical memory and resource management issues:
- Event listeners (
resize,click) are attached but never removed setIntervalis started but never cleared- No cleanup/disposal mechanism exists to free resources
- Large data structures are continuously added to the resources map without bounds
Consider adding a cleanup method:
class ResourceManager {
private resources: Map<string, any[]> = new Map();
private eventListeners: { [key: string]: EventListener } = {};
+ private intervalId: number;
constructor() {
// 创建大量事件监听器但没有清理机制
window.addEventListener('resize', this.handleResize);
document.addEventListener('click', this.handleClick);
// 启动定时器但没有清理
- setInterval(this.collectData, 1000);
+ this.intervalId = window.setInterval(this.collectData, 1000);
}
+ public dispose(): void {
+ // Remove event listeners
+ window.removeEventListener('resize', this.handleResize);
+ document.addEventListener('click', this.handleClick);
+
+ // Clear interval
+ window.clearInterval(this.intervalId);
+
+ // Remove element listeners
+ const element = document.getElementById('tracking-area');
+ if (element) {
+ Object.values(this.eventListeners).forEach(listener => {
+ element.removeEventListener('mouseover', listener);
+ });
+ }
+
+ // Clear resources
+ this.resources.clear();
+ this.eventListeners = {};
+ }Committable suggestion skipped: line range outside the PR's diff.
