Implicit type coercion

Implicit type coercion occurs when a language like JavaScript automatically converts values from one data type to another to perform an operation, without explicit instruction from the developer. While intended as a convenience, implicit coercion often results in subtle bugs or unexpected behavior—for example, the loose equality operator (==) in JavaScript converts types implicitly, leading to confusing comparisons. Developers might unintentionally rely on coercion, introducing logical errors, unpredictable outcomes, and complicating debugging and maintenance.

To fix implicit type coercion bugs, explicitly perform type conversions or comparisons, clearly specifying intended behavior in your code. Replace loose equality operators (==) with strict equality operators (===) in JavaScript to prevent unintended type conversions. Utilize strict mode or tools like TypeScript to enforce explicit typing and avoid coercion-related errors proactively. Regularly review and test your code logic, focusing on comparisons and arithmetic operations, ensuring clarity, correctness, and predictable behavior.
