&& (logical AND)

Compares two expressions and returns true only if both evaluate to true. Returns false if one or both evaluate to false. The following list shows all possible combinations:

true && false // Evaluates false because the second is false
false && true // Evaluates false because the first is false
true && true // Evaluates true because both are true
false && false // Evaluates false because both are false
