Study Notes
Boolean Data Type
- Boolean data type holds only two values: true or false.
- These values result from comparisons.
Comparison Operators
-
Equality operator (==): Checks if two values are equal.
-
Example: 100 == "100" returns true.
-
Strict equality operator (===): Checks both value and type for equality.
-
Example: 100 === "100" returns false (different types).
-
Inequality operator (!=): Checks if two values are not equal.
-
Example: 1 != 1 returns false.
-
Strict inequality operator (!==): Checks both value and type for inequality.
-
Example: 1 !== "1" returns true (different types).
