Remove Last Item From Slice in Go

Another way to change the data in a slice is by re-slicing it, which removes the last element:

threeArr := []int{1, 4, 6}

// Remove last element:
threeArr = threeArr[:len(threeArr)-1]

// threeArr is now {1, 4}

// Remove last element again:
threeArr = threeArr[:len(threeArr)-1]

// threeArr is now {1}
