tail

tail() focus on subarray that remains after skipping the first element. It complements head.

When writing to an empty array, an element will be created. When updating to an empty array, it will result in an empty array.

const focus = flow(eq<string[]>(), tail())
view(focus)(['a', 'b', 'c']) // ['b', 'c']
view(focus)([]) // []
command(focus, REMOVE)(['a', 'b', 'c']) // ['a']
put(focus, ['P', 'Q'])(['a', 'b', 'c']) // ['a', 'P', 'Q']
