Code Inspection: Useless trailing comma
Configure inspections: Settings | Editor | Inspections
Show intention actions: AltEnter
Reports the trailing commas in parameters 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.
Place the caret at the highlighted line and press AltEnter or click
.
Click the arrow next to the inspection you want to suppress and select the necessary suppress action.
