There are five types of Javascript operator which is more important we are goanna to focus on these.

Types of Operators:
  1. Arithmetic Operators

  4. Bitwise Operators
  5. Assignment Operators

Operator

Example

Same As

=

x = y

+=

x += y

x = x + y

-=

x -= y

x = x * y

/=

x /= y

x = x / y

%=

x %= y

x = x % y

**=

x **= y

x = x ** y
