Why does slices.Delete() in golang copy the next element?-CodePudding

Sample code:

func main() {
    bar := []string{"Monday", "Tuesday", "Wednesday"}
    slices.Delete(bar, 0, 1) // I want to delete 'Monday'
    fmt.Println(bar)         // prints [Tuesday Wednesday Wednesday]
}

I don't understand why I get a copy of 'Wednesday'. I was expecting a two-element slice.

CodePudding user response：

slices.Delete returns the modified slice. You should use it as:

bar=slices.Delete(bar, 0, 1)

This is because the delete operation shifts the elements in the slice, and then returns a shorter slice, but the original slice bar remains the same.
