= assignment operator
== comparison operator. Compares if values are equal
=== strict equality equality. Compares if values and data types are equal
!= inequality operator
!== strict inequality operator

Assignment Operator = (Assignment) Assigns a value to a variable
The right side is evaluated first, then assigned to the left side
Example:
let x = 5 assigns the value 5 to variable x

Comparison Operators
== (Loose Equality/Abstract Equality)
Compares values for equality after performing type coercion
JavaScript automatically converts operands to the same type before comparison
Examples:
5 == "5" returns true (string "5" is converted to number 5)
true == 1 returns true (boolean true becomes 1)
null == undefined returns true

=== (Strict Equality)
Compares both value and data type without any type conversion
No type coercion occurs - both operands must be exactly the same type and value
Examples: 5 === "5" returns false (number vs string)
5 === 5 returns true
null === undefined returns false

Inequality Operators
!= (Loose Inequality)
Returns true if operands are not equal after type coercion
Opposite of ==
Example: 5 != "6" returns true, but 5 != "5" returns false

!== (Strict Inequality)
Returns true if operands are not equal in value OR not the same type
Opposite of ===
No type coercion occurs
Example: 5 !== "5" returns true (different types)
