WebSlices are an important data type in Go, giving a more powerful interface to sequences than arrays. Unlike arrays, slices are typed only by the elements they contain (not the number of elements). To create an empty slice with non-zero length, use the builtin make. Here we make a slice of string s of length 3 (initially zero-valued).
