2. Comparison Operators
| Operator | Name | Example |
|---|
| == | Loose Equality | '5' == 5 → true |
| === | Strict Equality | '5' === 5 → false |
| != | Loose Inequality | '5' != 5 → false |
| !== | Strict Inequality | '5' !== 5 → true |
| > | Greater than | 5 > 3 → true |
| < | Less than | 5 < 3 → false |
| >= | Greater or equal | 5 >= 5 → true |
| <= | Less or equal | 5 <= 4 → false |

Always use === (strict equality)! The loose equality (==) does type coercion which can lead to unexpected results.
3. Logical Operators
| Operator | Name | Example |
|---|
| && | AND | true && false → false |
| || | OR | true || false → true |
| ! | NOT | !true → false |
| ?? | Nullish Coalescing | null ?? 'default' → 'default' |
