How to Efficiently Access and Remove the Last Element of a Slice in Go?

Extracting the Last Element of a Slice: A Go Perspective

Retrieving the final element of a slice is a common task in Go programming. While the provided solution using slice[len(slice)-1:][0] is functional, it can appear complex.

Efficient Approaches

There are more straightforward alternatives for both accessing and removing the last element of a slice:

Accessing the Last Element:

To retrieve the last element, simply use the expression:

sl[len(sl)-1]

This returns the value of the last element without creating a new slice.

Removing the Last Element:

To remove the last element from the slice, assign a new slice without it:

sl = sl[:len(sl)-1]

This method updates the original slice to exclude the last element.
