How to determine whether slice is empty in golang

Slice in Go language relies on arrays. Its bottom layer is arrays, so slices have the advantages of arrays. And slice supports appending elements to the slice through append. When the length is not enough, it will be dynamically expanded. By slicing the slice again, a smaller slice structure can be obtained, which can be iterated, traversed, etc.

Let’s take a look at the method of judging whether a slice is empty in golang:

The implementation code of judging whether a slice is empty in golang:

 // 切片
    slice := make([]int, 0, 0)
    if len(slice) == 0 {
        println(`这是个空切片`)
    }}
