to_sentence(options = {})

Converts the array to comma-seperated sentence where the last element is joined by the connector word. Options:

  • :connector: The word used to join the last element in arrays with two or more elements (default: "and")

  • :skip_last_comma: Set to true to return "a, b and c" instead of "a, b, and c".
