JavaScript Logical Operators

JavaScript Logical Operators are used to evaluate two or more expressions, and the result is a boolean value either true or false. The logical operators in JavaScript are &&, ||, and !.

NameOperatorExample
Logical AND&&true && false
Logical OR`
Logical NOT!!true

In the example column, the expressions are evaluated, and the result is a boolean value.

The && operator returns true only if both expressions are true, otherwise it returns false.

The || operator returns true if either of the expressions is true, and returns false only if both expressions are false.

The ! operator reverses the value of an expression, if the expression is true then the result is false, and vice versa.
