Range

range() iterates over elements in a variety of data structures. range() on arrays and slices provides both the index and value for each entry.

We ignore variables using the blank identifier _ (underscore).

range() on a map iterates over key/value pairs; can also iterate over just the keys of a map.

range() on strings iterates over Unicode code points. The first value is the starting byte index of the rune and the second the rune itself.
