自我介绍一下，小编13年上海交大毕业，曾经在小公司待过，也去过华为、OPPO等大厂，18年进入阿里一直到现在。
深知大多数前端工程师，想要提升技能，往往是自己摸索成长或者是报班学习，但对于培训机构动则几千的学费，着实压力不小。自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！
因此收集整理了一份《2024年Web前端开发全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友，同时减轻大家的负担。
既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，基本涵盖了95%以上前端开发知识点，真正体系化！
由于文件比较大，这里只是将部分目录截图出来，每个节点里面都包含大厂面经、学习笔记、源码讲义、实战项目、讲解视频，并且会持续更新！
如果你觉得这些内容对你有帮助，可以扫码获取！！（备注：前端）
最后
一个好的心态和一个坚持的心很重要，很多冲着高薪的人想学习前端，但是能学到最后的没有几个，遇到困难就放弃了，这种人到处都是，就是因为有的东西难，所以他的回报才很大，我们评判一个前端开发者是什么水平，就是他解决问题的能力有多强。
