## Let's Gogogogogo！

* **[如何让idea快速实现接口](https://www.bilibili.com/video/BV19e4y1A7DD)**

  _虽然go没有`imple`关键字，但依旧不影响gopher发挥._

* **[可变参数`...`操作神奇切片](https://www.bilibili.com/video/BV1CA41167dM)**

  _神奇...的用法._

* **[interface的nil陷阱](https://www.bilibili.com/video/BV1uT41197i4)**

  _golang的`interface{}`可没有ts的`any`省心._

* **[给函数返回值起好名字](https://www.bilibili.com/video/BV1dT411D7vy)**

  _好的习惯会给无聊代码带来一阵清风._

* **[你关注过range后面的表达式吗](https://www.bilibili.com/video/BV15Y411i7oz/)**

  _不同于for，range后接的表达式只会被求值一次._

 * **[永远不要在循环中更新map](https://www.bilibili.com/video/BV15Y411i7oz)**

   _map是动态数据类型，你根本不知道自己的数据存储在个桶._

 * **[如何更新map中的struct](https://www.bilibili.com/video/BV1ER4y1B7WY/)**

    _map如果存储struct作为value，不能修改它的字段._

 * **[如何优雅地实现继承](https://www.bilibili.com/video/BV1Ge4y1w7eL)**

    _结构体嵌套有用，但是并非处处有用._

 * **[方法接收器悖论](https://www.bilibili.com/video/BV1Ys4y1a7xy/)**

    _深刻摸索两种方法集和接口的关系._ 

 * **[闭包为何具有记忆效应](https://www.bilibili.com/video/BV14D4y1w7xP/)**

    _利用内存逃逸分析解释闭包的变量记忆._ 

 * **[责任链带你逃离IF地狱](https://www.bilibili.com/video/BV13A411U7Z4/)**

    _如果业务层条件判断过多，请选择责任链吧._ 

 * **[探索map循环随机的根本原因](https://www.bilibili.com/video/BV1JT411D7gB/)**

    _从golan源代码简单看看为何map是没有顺序的._ 

 * **[优雅的多用例单元测试](https://www.bilibili.com/video/BV1Wj411A7CN/)**

    _如果针对同一函数测试用例过多，试试表驱动测试._ 

 * **[利用Fuzz Test消灭BUG](https://www.bilibili.com/video/BV1KT411U7tF/)**

    _单元测试不放心，试试模糊测试._ 

 * **[利用卫语句消除IF嵌套](https://www.bilibili.com/video/BV18e4y1c7GW/)**

    _如果某些分支为异常层，就利用Guard Clause让他们提前返回吧._ 

 * **[如何漂亮地实现依赖注入](https://www.bilibili.com/video/BV1Db411X7dU/)**

    _复杂项目不要手动注入依赖，选择WIRE解放生产力._
