multilineAmbiguities

Reports ambiguous multiline expressions that could be misinterpreted.

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

When a line ends with an expression and the next line starts with certain characters (parentheses, brackets, or template literals), JavaScript may interpret them as a continuation of the previous line rather than separate statements. This can lead to unexpected behavior and runtime errors that are difficult to debug.

When Not To Use It

Section titled “When Not To Use It”

If you consistently use semicolons and have tooling that enforces their presence, this rule may be unnecessary. However, having this rule enabled provides an additional safety net against accidental multiline ambiguities.
