* __Others__: `Conditional/Ternary(?:)`, `instanceof` * __Others__: `Conditional/Ternary(?:)`, `instanceof`
**Ternary because it work on the functionality of If Then Else i.e If condition is right then first alternative anotherwise the second one ** **Ternary because it work on the functionality of If Then Else i.e If condition is right then first alternative anotherwise the second one **
While most of the operations are self-explanatory, the Conditional (Ternary) Operator works as follows: While most of the operations are self-explanatory, the Conditional (Ternary) Operator works as follows:
`expression that results in boolean output ? return this value if true : return this value if false;` `expression that results in boolean output ? return this value if true : return this value if false;`
