JavaScript provides us 3 logical operators: and, or and not.Logical andReturns true if both operands are true:<expression> && <expression>For example:a === true && b > 3The cool thing about this operator is that the second expression is never executed if the first evaluates to false. ...
In a logical operator, if you use the AND operator, the compound expression returns true if both expressions are true. If you use the OR operator then the compound expression returns true if either is true. If you use the NOT operator, the value returns true if either expression is ...
Comparison operators are used in logical statements to determine equality or difference between variables or values. Given that x = 5, the table below explains the comparison operators:OperatorDescriptionComparingReturnsTry it == equal to x == 8 false Try it »...
Note: In JavaScript, == is a comparison operator, whereas = is an assignment operator. If you mistakenly use = instead of ==, you might get unexpected results.2. Not Equal To OperatorThe not equal to operator != evaluates totrue if the values of the operands aren't equal. false if ...

Here thelateroperator(\mathop {\blacktriangleright })ensures that we “go down a step” when unfolding the recursive definition. Intuitively, this ensures that\mathbf {Type}at step-indexiis only defined in terms of\mathbf {Type}at strictly smaller step-indices,j < i, and thus that the equa...
