stage 4 if else statement

var money = 9; var today = 'Friday'

if ( money >= 100 || today !== 'Friday' ) { alert("Time to go to the theater");
} else if ( money >= 50 || today !== 'Friday' ) { alert("Time for a movie and dinner");
} else if ( money > 10 || today !== 'Friday' ) { alert("Time for a movie");
} else if ( money > 5 || 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."); }

still doesn't work.

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

if ( money >= 100 || today !== 'Friday' ) {
  alert("Time to go to the theater");    
} else if ( money >= 50 || today !== 'Friday' ) {
  alert("Time for a movie and dinner");    
} else if ( money > 10 || today !== 'Friday' ) {
  alert("Time for a movie");   
} else if ( money > 5 || 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.");
}

In JavaScript the || means OR. if ( money >= 100 || today !== 'Friday' ) is going to evaluate to true any time it isn't Friday regardless of how much money you have. I suspect all the || need to be changed to && for the logic to work.

var money = 9;
var today = 'Friday'

// The first if statement used to be: if ( money >= 100 || today === 'Friday' )
// but since we want the to test the money AND today variables
// we replace "||", which means "OR", with "&&", which means "AND"
// We do this for the next two else if statements as well.

// The last thing we need to do is change: else if ( today !== 'Friday' )
// to else if ( today === 'Friday' )

if ( money >= 100 && today === 'Friday' ) { 
  alert("Time to go to the theater");    
} else if ( money >= 50 && today === 'Friday' ) {
  alert("Time for a movie and dinner");    
} else if ( money > 10 && today === 'Friday' ) {
  alert("Time for a movie");   
} 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.");
}
