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.
