Golang

My learning notes and practices for Go language.

Golang不愧是现代的C语言, 系统的学习下来, 真是足够简洁, 而又灵活且强大, 为服务器应用而生. 迫不及待想用它开发点什么了!!

  • 罗列几项我认为的关键特性如下:
    • 编译型语言, 仅支持静态链接于是可以run everywhere; 编译过程要么error要么pass, 于是终于不用再纠结warning到底要不要解决的问题.
    • 没有class与继承等概念, 面向对象特性都通过method和interface来实现(封装通过命名的大小写来实现). method绑定到类型仅仅是简单的定义一个属于类型的函数即可, 非常方便扩展.
      • 这一点感觉就是在怼C++/Java中的过度抽象, 最终目的是为了更好更方便的解决问题, 一切皆对象未必是最好的solution.
    • 简洁又强大的goroutine/channel!
    • 完善的profile工具, 包括对cpu, memory, block的profile, 以及race detector工具. 性能分析不再是问题!
    • 极简的test框架
  • 个人不太喜欢的特性:
    • 固定的workspace结构: 一台机器上同时还不能有2个workspace了?
