What is the Go
way for extracting the last element of a slice
?
var slice []int
slice = append(slice, 2)
slice = append(slice, 7)
slice[len(slice)-1:][0] // Retrieves the last element
The solution above works, but seems awkward.

For just reading the last element of a slice:
sl[len(sl)-1]
For removing it:
sl = sl[:len(sl)-1]
See this page about slice tricks
Bit less elegant but can also do:
sl[len(sl)-1: len(sl)]
