在北京、天津的前端工程师（我主攻javascript，有一年的web开发经验）待遇分别怎么样，，急求大侠们给解决
如果只会一门技术的话，会不会太窄了呢？好的Web前端开发工程师，需要会很多东西的哦，处理客户端和服务器端的交互，做好页面优化，做好SEO，javascript方向我有一哥们在北京搞这个，你有工作经验，如果技术可以的话，北京至少5000+吧。
发展的话，我了解到的是处理客户端和服务器端的交互，做好页面优化，做好SEO，还要会基本的HTML，Javascript，CSS等Web前端技术，如果还会网页设计就更好了，企业喜欢懂后台开发，懂数据库的还懂前端开发，还懂页面设计，还懂SEO优化的，当然会了这些，我感觉工资就会很高了。
