How do you access and manipulate the last element of a slice in Go?

Extracting the Final Element of a Slice the Go Way

In Go, accessing the last element of a slice can be achieved through various approaches. A seemingly cumbersome method involves using slice[len(slice)-1:][0].

However, for simply reading the last element, a more concise solution is:

sl[len(sl)-1]

If the intention is to remove the last element, the following code accomplishes it:

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