Code Inspection: Useless trailing comma

Reports the trailing commas in parameter lists and closures' use lists that do not bring any benefit.

  • In a single-line list, a trailing comma is redundant and can be removed.

  • In a multiline list, if no line break is provided after a trailing comma, it becomes impossible to easily add, remove, or move lines.

Suppress an inspection in the editor

  1. Place the caret at the highlighted line and press Alt+Enter or click the Intention action icon.

  2. Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
