Unary Operators:

1 Increment operators (++): JavaScript uses an increment operators ( ++ ) to increasing the value of variable
with ( + 1 ).
Increment Operators are two types:

i Pre- Increment operator (++a): It is use for increasing value before use of variable.
ii Post- Increment operator (a++): It is use for increasing value after use of variable.
2 Decrement operators (--): JavaScript uses an decrement operators ( -- ) to decreasing the value of variable
with ( - 1 ) .

i Pre- decrement operator (++a): It is use for decreasing value before use of variable.
ii Post- decrement operator (a++): It is use for decreasing value after use of variable.
Comparison Operators: JavaScript uses an comparison operators to compare values between two variables.
There are many type of comparison operators:
• Greater than(>)

• Greater than and Equal(>=)
• Smaller than(<)
• Smaller than and Equal(<=)
• Equal to(==)

• Equal to & Type(===)
• Not Equal to(!=)
• Not Equal to and Type(!==)
Logical Operators: JavaScript uses an Logical operators to compare and given a boolean value.
There are three types of Logical operators:
• Logical AND (&&)

• Logical OR ( | | )
• Logical NOR ( ! )

Types of JavaScript Operators
There are different types of JavaScript operators:

• Arithmetic Operators
• Assignment Operators
• Comparison Operators
• String Operators

• Logical Operators
• Bitwise Operators
• Ternary Operators
• Type Operators
