Difference between != and !== operator in JavaScript
Feature | != (Loose Inequality) |
!== (Strict Inequality) |
Type Coercion | Converts values to the same type for comparison. | Compares values without changing their types. |
Example | 5 != "5" is false |
5 !== "5" is true |
Usage Recommendation | Use with caution as it may lead to unexpected results due to type coercion. | Preferred in most cases to ensure both value and type are considered. It’s more explicit and reduces the chance of unexpected behavior. |
