Something's wrong with this script. The value in the variable money is 9. But if you preview this script, the browser di

script.js 
const money = 9;
const today = 'Friday'

if ( money > 10 && today === 'Friday' ) {
  alert("Time to go to the theater.");    
} else if ( money >= 50 || today === 'Friday' ) {
  alert("Time for a movie and dinner.");    
} else if ( today == 'Friday' ) {
  alert("It's Friday, but I don't have enough money to go out.");   
} else {
  alert("This isn't Friday. I need to stay home.");
}

The first else if is now passing in your code because one of these conditions is passing.

money >= 50 || today === 'Friday'

You want both those to pass in order to go to movie and dinner.

Hi Ange!

The trick is really to think about the logic!

It looks like you're on the right track (2 out of 3).

This passes:

const money = 9;
const today = 'Friday'

if ( money > 10 && today === 'Friday' ) {
  alert("Time to go to the theater.");    
} else if ( money >= 50 && today === 'Friday' ) {
  alert("Time for a movie and dinner.");    
} else if ( today === 'Friday' ) {
  alert("It's Friday, but I don't have enough money to go out.");   
} else {
  alert("This isn't Friday. I need to stay home.");
}

But this would be even better logic, really:

const money = 9;
const today = 'Friday'

if ( money >= 50 && today === 'Friday' ) {
  alert("Time for a movie and dinner.");
} else if ( money > 10 && today === 'Friday' ) {
  alert("Time to go to the theater.");    
} else if ( today === 'Friday' ) {
  alert("It's Friday, but I don't have enough money to go out.");   
} else {
  alert("This isn't Friday. I need to stay home.");
}

Because the first way, if you had $100.00 it would suggest going to the theater, but you can actually afford dinner and a movie!?! Does that make sense?

(BTW, the second way passes also...)

I hope that helps.

Stay safe and happy coding!
