Logical operators combine or invert boolean conditions. They are used to build compound conditions — checks that require more than one thing to be true at the same time, or where either of two things being true is enough.

For a broader introduction to operators, see Operators.

AND#

The AND operator returns true only when both conditions are true. If either is false, the result is false.

int score = 7;
bool result = score > 5 && score < 10;  // true

score = 7
result = score > 5 and score < 10  # True

let score = 7;
let result = score > 5 && score < 10;  // true

OR#

The OR operator returns true when at least one condition is true. It only returns false when both are false.
