我相信我的观点遗漏了一些东西，但我尝试HttpStatusCode.Ok从 Axios Enum 调用我实现的方式是

import { HttpStatusCode } from 'axios'

console.log(HttpStatusCode.Ok)

但我得到了奇怪的错误Cannot read properties of undefined (reading 'Ok')

我\xe2\x80\x99m正在学习Golang，我停了下来并让我困惑。

package main\n\nimport "fmt"\n\nfunc main() {\n    month := [...]string{1: "Jan", 2: "Fab", 3: "March", 4: "April", 5: "May", 6: "June", 7: "July", 8: "Aug", 9: "Sep", 10: "Oct", 11: "Nov", 12: "Dec"}\n    fmt.Println(cap(month))\n    summer := month[6:9]\n    Q2 := month[4:7]\n    fmt.Println(cap(Q2))\n    fmt.Println(len(Q2))\n\n    fmt.Println(cap(summer))\n    fmt.Println(len(summer))\n}\n\n

输出是

13\n9\n3\n7\n3\n

月切片有 12 个元素，但cap(month)和len(month)返回13，为什么？
