# 简介

这本小书是我准备前端面试的时候收集的一些问题，与我自己整理的解答。整理这本书，一方面是为了自己能够梳理一下现在的知识脉络，认真准备面试，另一方面是为了方便各位正在准备面试的同学们。

本书的解答除了参考相关资料外，还有一些自己的理解。我不保证我的理解一定正确，也欢迎大家帮助我完善我的解答，纠正我的错误，感激不尽！

同时，如果你是正在面试的同学，也欢迎你分享你的面试经验，我会将你提供的有价值的问题添加到这本书的问题列表里，并附上你的解答。或许你不知道答案，我也欢迎你向我提问，互相成长\~

有任何问题或相关的分享与补充，欢迎到本书的 Github Repo 上提交 Issue，谢谢。Github Repo: <https://github.com/umaruio/fe-interview-cheat-sheet/issues>

献给每一个对技术有信仰的 FEer，和每一个相信童话的人\~
