You need to change the || (OR) in && (AND) , and in the last else if use the identical compare === here the code:

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.");

Try not to remove any operators from the code, though you will need to change some.

The trick to this one is to look at how the conditions being tested relate to the messages that would be output. And when more than one test is being made at the same time there are different ways to combine them:

  • the AND operator ("&&") means both tests must be true
  • the OR operator ("||") means one test can be false if the other is true.

Also a test for equality ("===") or inequality ("!==") might need to be changed if it did not make sense for the message.

For example:

if (color === "blue") { alert{"I sure am glad it is not blue!"): }

That code would not make sense. But if you changed the test operator to "!==" instead, it would.

So give the challenge another shot, and see if you can make each test (or test combination) make sense by substituting operators.
