会发现抛unknown escape sequence: ',说明人家解释型字符串根本不与\'一块玩。 上面两个示例估计就能理解什么是原生字符串什么 是解释型字符串了。 再看一下字符串的内存地址问题: func main() { var s string = "wait, who am I ?" var t string = "wait, who am I ?" fmt.Println("s address i...

Each name declares a type parameter, which is a new and different named type that acts as a place holder for an (as of yet) unknown type in the declaration. The type parameter is replaced with a type argument upon instantiation of the generic function or type. ...
