blockSequences

Prefer block style sequences over flow style sequences.

✅ This rule is included in the yaml stylistic and stylisticStrict presets.

Block style sequences use hyphens (-) to denote list items and are generally more readable for multi-item lists. Flow style sequences use brackets ([]) and are more compact but less clear in most cases.
