A unary operator is an operation with only one operand.
Plus sign (+) can function as an Addition Operator and also as a Unary Version in Javascript Objects.
As an arithmetic addition operator: It takes numerical values (literals or variables) as their operands and return a single numerical value.
Both + and - operators have unary versions, where they operate only on one variable.
When used in this fashion, + returns the number representation of the object, while - returns its negative counterpart
The unary plus operator converts its operand to Number type.
The unary negation operator converts its operand to Number type and then negates it.
