Expand description
Logical operators are typically used with Boolean (logical) values; when they are, they return a Boolean value.
However, the &&
and ||
operators actually return the value of one of the specified operands,
so if these operators are used with non-Boolean values, they may return a non-Boolean value.
More information:
And
The logical AND operator returns the value of the first operand if it can be coerced into false
;
otherwise, it returns the second operand.
Syntax: x && y
More information:
The logical OR operator returns the value the first operand if it can be coerced into true
;
otherwise, it returns the second operand.
Syntax: x || y
More information:
The nullish coalescing operator is a logical operator that returns the second operand
when its first operand is null or undefined, and otherwise returns its first operand.
Syntax: x ?? y
