Boolean Javascript

Question

Javascript beginner here, I keep getting a wrong answer to this question:

"First, figure out if we have enough slices now. Use a comparison operator to figure out if there are enough. Assign the result to the enoughSlicesNow variable."

//Variables are below//

var cakes = 5;
var slicesPerCake = 6;
var attendees = 60;
var bakers = 3;
var cakeBakingTime = 1;
var hoursLeftUntilParty = 5;

This is what I tried but it will not accept:

(cakes * slicesPerCake)>= attendees 

var enoughSlicesNow = false

"Assign the result to the enoughSlicesNow variable" you are always assigning false to enoughSlicesNow, not the result of the comparison. — Felix Kling

Looks like you need:

var enoughSlicesNow = (cakes * slicesPerCake) >= attendees;

You can do like this using ternary operator

var cakes = 5;
var slicesPerCake = 6;
var attendees = 60;
var bakers = 3;
var cakeBakingTime = 1;
var hoursLeftUntilParty = 5;


 var enoughSlicesNow = (cakes * slicesPerCake) >= attendees ?true:false
alert(enoughSlicesNow)

Do you want like this...

    var cakes = 5;
    var slicesPerCake = 6;
    var attendees = 60;
    var bakers = 3;
    var cakeBakingTime = 1;
    var hoursLeftUntilParty = 5;
    
    
     var enoughSlicesNow = (cakes * slicesPerCake)>= attendees;
     if(enoughSlicesNow ==true){
         alert('Enough');
       }
    else
    {
      alert('Not enough');
    }

if(true == x) should always be rewritten to if(x), unless you are like using === and you know what you are doing

it is also possible to compare with true.
