JavaScript 根据数组对象的某个 指定属性 分组合并，并累加金额
最新发布
zhangyao940330的博客

item } 浅拷贝原对象的所有属性（如 id、name），合并时仅更新金额，其他属性保留第一个分组对象的值（若需保留所有属性，可修改为数组存储，如 name: [‘苹果’, ‘香蕉’]）。分组逻辑：用 Map 存储分组，键为 groupKey 的值（如 ‘水果’），值为合并后的对象。Map 比普通对象更安全（避免键名冲突，支持数字 / 对象等类型的键）。缺失金额或非数字（如 undefined、‘abc’）视为 0。字符串金额（如 ‘8’）自动转为数字；扩展需求：保留分组内所有非金额属性。

javascript 性能优化实战：异步和延迟加载
小伙伴们全都Lucky！
12-11 930
本文探讨JavaScript性能优化中的异步加载与延迟加载技术。异步加载通过async/defer属性或动态创建script元素避免阻塞渲染；延迟加载则利用IntersectionObserver API按需加载非关键资源。二者结合可显著提升性能：异步加载核心脚本确保交互流畅，延迟加载减少初始请求量。实践表明，该方案能降低DOMContentLoaded时间30%以上，减少初始加载量90%，但需注意async脚本的执行顺序问题和延迟加载的回退处理。文中提供了完整的代码实现示例。
