go語言標識符區(qū)分大小寫

關鍵字:共25個

break    default        func    interface  select
case     defer          go      map        struct
chan     else           goto    package    switch
const    fallthrough    if      range      type
continue for            import  return     var

一些go內(nèi)建的常量,變量,函數(shù)

Constants:  true  false  iota  nil

Types:  int      int8      int16      int32      int64
        uint     uint8     uint16     uint32     uint64     uintptr
        float32  float64   complex128 compllex64
        bool     byte      rune       string     error

Functions:
make     len      cap    new    append    close
delete   complex  real   image  painc     recover

Go語言通過標識符首字母大小寫區(qū)分變量可見性:
小寫字母開頭是 私有變量 ,大寫字母開頭是 公有變量
camel case:駝峰式命名 eg:"HttpDefaultHandler"
