Are variables of the same value but different types equal?

values_equal_regardless_of_type.dart

typedef A = String;
typedef B = String;

void main() {
  A a = "xxx";
  B b = "xxx";
  if (a == b) {
    print("bad: variables with the same value are equal");
  } else {
    print("excellent! variables with different types are not equal");
  }
}

// bad: variables with the same value are equal

if (a === b) {
  console.log("bad: variables with the same value are equal");
