The aim of this puzzle: Use the “and” logical operator && inside the if statement to check if 2 separate conditions are both true.
Walkthrough of the solution: The && logical operator is used to check if 2 separate conditions are true. It returns true only if both conditions are true. For example:

if (day === 'weekday' && holiday === 'no') {
  print('You have to go to work today');
}

The if statement checks to see if day is equal to 'weekday' AND if vacation is equal to 'no'. The string 'You have to go to work today' will be printed only if both conditions are true. If 1 or both conditions are false, then the code in the if statement’s code block will not run.

In this puzzle, the code and key variables are declared in hidden code. code will always have the value 42, and key uses pickRandom() to choose between 'yes' or 'no'. The two print() statements at the top of the code will print these values out.

To complete the puzzle, edit the 2nd if statement’s test to check if key === 'yes' && code === 42.
Sample code solution:
(Tap below to reveal)

print('The code is ' + code);
print('Key found: ' + key);

if (key === 'no' && code === 42) {
    print('Unlock unsuccessful.');
}

if (key === 'yes' && code === 42) {
    print('Unlock successful');
}

var code = 42;
var key = pickRandom(['yes', 'no']);

Hi there,

Thanks for flagging! I fixed the typo :smile:

Hidden code is:

var code = 42

var key = pickrandom([
‘yes’,
‘no’
]);
