Operators allow you to get one or more simple expressions and combine them to form a more complex expression.

We can classify operators based on the operands they work with.

Most operators work with 2 operands:

• Addition (+)
• Subtraction (-)
• Division (/)
• Remainder (%)
• Multiplication (*)
• Exponentiation (**)
• Assignment (=)
• Comparison operators (<, <= etc)
• Equality checks (==, !== etc)
• Logical and and or
• instanceof
• in

Some operators work with 1 operand:

• Increment (++)
• Decrement (--)
• Unary negation (-)
• Unary plus (+)
• Logical not (!)
• new
• delete
• typeof
• await
• The spread operator

Just one operator works with 3 operands: the ternary operator.
