How to select a part of a slice
Go allows us to select parts of a slice, provided that all desired elements are next to each other. This can be pretty handy when we select a range of elements and we do not want to give their indexes one by one. In Go, we select a part of a slice by defining two indexes: the first one is the beginning of the selection, whereas the second one is the end of the selection, without including the element at that index, separated by :.
Note: If we want to process all the command-line arguments of a utility apart from the first one, which is its name, we can assign it to a new variable (
arguments := os.Args) for ease of ...
