Hello, yes it is basic for Boolean logic.

1)

What does this condition evaluate to: true or false? 
( true && false )

it Equals 1 * (-1)

2)

Given the following code, what will appear in the browser's console? 

var x = 10;
var y = 20;
if (  x < 10 && y > 10 ) {
  console.log('The condition passes.');
} else {
  console.log('The condition fails.');
}

The if means: is x smaller than 10 and is y higher than 10? No? so the program switch to the else.

3)

Complete the code below so that both conditions must be true for the alert message to appear: 

if ( loggedIn === true 
[           ]
 level === 'admin') {
  alert("Access granted.");
}

&& = and

|| = or

4)

What does this condition evaluate to: true or false? 
( true || false )

This is what TeamTreeHouse told me: :D When using the OR operator only one of the conditions needs to be true.

Was it helpful for you? You can give me some points :)
