有哪些主打web前端开发的公司 或者前端厉害的公司
推荐回答（1个）
Web前端开发是从网页制作演变而来的
Web前端开发的工作职责
1、使用Div+css并结合Javascript负责产品的前端开发和页面制作；[1]
2、熟悉W3C标准和各主流浏览器在前端开发中的差异，能熟练运用DIV+CSS，提供针对不同浏览器的前端页面解决方案；
3、负责相关产品的需求以及前端程序的实现，提供合理的前端架构；
4、与产品、后台开发人员保持良好沟通，能快速理解、消化各方需求，并落实为具体的开发工作；
5、了解服务器端的相关工作，在交互体验、产品设计等方面有自己的见解。
Web前端优化
尽量减少HTTP请求 (Make Fewer HTTP Requests)
减少 DNS 查找 (Reduce DNS Lookups)
避免重定向 (Avoid Redirects)
使得 Ajax 可缓存 (Make Ajax Cacheable)
延迟载入组件 (Post-load Components)
预载入组件 (Preload Components)
减少 DOM 元素数量 (Reduce the Number of DOM Elements)
切分组件到多个域 (Split Components Across Domains)
最小化 iframe 的数量 (Minimize the Number of iframes)
杜绝 http 404 错误 (No 404s)
前端开发和web前端开发无区别，叫法不一样
