What code must I write so that the alert message "Its Friday,but i don't have enough money to go out"

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 ( 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."); }

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 ( 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.");
}

Hi,

You need to adjust multiple statements in this challenge.

Your code should look something like: 

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 < 10 && 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.");
}

Read through this code line by line and see why this makes sense. We have a unit of 9 money and today is Friday.

The code is now saying:

  • If we have 100 or more money AND today is Friday then lets go to the theater.
  • If we have 50 or more money AND it's Friday lets go for a movie and dinner
  • If we have more than 10 money AND it's Friday, lets go for a movie
  • If we have less than 10 money AND it's Friday, then we don't have enough money to go out
  • Otherwise, it's not Friday and we stay home.

I hope this helps

hi Maxwell, it is like John said. with this in mind, you could do something like this:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Money</title>
</head>
<body>
<label for="m">money</label>
<input type="text" id="m" value="9"/>
<label for="today">day</label>
<input type="text" id="today">
<button id="money">answer</button>
<script>
    var answer = {
        day: "friday",
        one: "Time to go to the theater",
        two: "Time for a movie and dinner",
        three: "Time for a movie",
        four: "This isn't Friday. I need to stay home.",
        five: "It's Friday, but I don't have enough money to go out",
        whatDay: function (d) {var day = d.toLowerCase();return day === this.day;}};

    var m = document.getElementById("money");
    m.addEventListener("click", function () {
        var money = document.getElementById("m").value;
        var today = document.getElementById("today").value;
        today = today.toLowerCase();
        if (money >= 100 && answer.whatDay(today)) {
            alert(answer.one);
        } else if (money >= 50 && answer.whatDay(today)) {
            alert(answer.two);
        } else if (money >= 10 && answer.whatDay(today)) {
            alert(answer.three);
        } else if (!answer.whatDay(today)) {
            alert(answer.four);
        } else {
            alert(answer.five);
        }
    });
