combinedPushes

Reports consecutive array.push() calls that could be combined into a single call.

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

Multiple consecutive .push() calls on the same array can be combined into a single call. Using .push(a, b, c) is more concise than separate .push(a), .push(b), .push(c) calls.
