Type Coercion: JavaScript tries to convert "abc" to a number for multiplication but fails, resulting in NaN (Not-a-Number).

Output: NaN (since "abc" cannot be converted to a valid number for arithmetic).

Key Point: Strings that aren’t numeric yield NaN in math operations.

Fix: Check input types before arithmetic (e.g., if (!isNaN(str))).
