Error message: wrong comparison token


#1



introduction to functions lesson 12


I just forgot about this lesson and moved on, but I keep getting an error message every time I try to save the code, and I don't know why:

Oops, try again. It looks like sleepCheck() isn't returning "You're getting plenty of sleep! Maybe even too much!" when numHours is 10. Check your if / else syntax and whether you're using the correct comparison operator.

I don't know why its doing this... can anyone help me around this bug? This is my code:


 
// Write your function below. 
// Don't forget to call your function!
var sleepCheck = function(numHours) {
    if (numHours >= 8) {
        return "You're getting plenty of sleep!  Maybe even too much!";
    } else { 
        return "Get some more shut eye!";
    }
};
sleepCheck(10);
sleepCheck(5);
sleepCheck(8);

@gamersclash,

######They ask
#"You're getting plenty of sleep! Maybe even too much!" 
######You use
#"You're getting plenty of sleep!  Maybe even too much!"

???... I'm not sure what you're saying... how can I get around or fix it?

You have to use the EXACT text's as they prescribe in the Instructions.....
Thus
you will have to remove 1 space-character between the EXCLAMATION-marker and the word MAYBE

In the coming couple of sections that will be the case !!!!!!
- EXACT text's
- if they ask you dispay.... you use the console.log() Method
- if they ask you to return.... you use the return statement...

Here an explanation of the usage of a function
Familiarize yourself with the meaning of
--parameter,
--parameter as =local= variable in the FUNCTION-BODY
--argument,
-- function call using 1 or more arguments
-- how to Display a VALUE received from the return statement....

the FUNCTION talk

var myFunc = function( param1, param2) {
       //Begin of  anonymous FUNCTION-BODY
       //VARIABLE -myFunc- has an -anonymous function- assigned
       //this -anonymous function- has 2 PARAMETERS param1 and param2
       //param1 and param2 PARAMETERS are used 
       //as -local- VARIABLES throughout the FUNCTION-BODY

      console.log( param1 + " and " + param2 ) ;

      //End of anonymous FUNCTION-BODY
};

If you want to call/execute the anonymous function
you will have to add a pair of parentheses to the variable myFunc
like
myFunc();
As the anonymous function was defined
as having 2 parameters
you have to provide 2 arguments
in our case 2 string VALUES "Alena" and "Lauren"
like
myFunc("Alena","Lauren");

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

function with 1 parameter using return-statement

var myFunction = function( param1 ) {
       //Begin of FUNCTION-BODY
       //myFunction =function= has 1 PARAMETER param1
       //this param1 PARAMETER is used as a -local- VARIABLE
       //throughout the FUNCTION-BODY

      return param1;

      //End of FUNCTION-BODY
      };

you have defined a myFunction function
which takes 1 parameter param1
this param1 parameter is used
as a variable throughout the FUNCTION-BODY.

If you want to call/execute this myFunction function
and this myFunction function was defined
as having 1 parameter param1
you will have to provide 1 argument
in our case a "number VALUE" 4
myFunction( 4 );

some quotes from the outer-world:

**argument is the value/variable/reference being passed in,
parameter is the receiving variable used within the function/block**

OR

**"parameters" are called "formal parameters",
while "arguments" are called "actual parameters".**

============================================

As you are using the return-statement in your myFunction function
you will only get a return-value no-display.
You can however capture this return-value in a variable
and then use the console.log()-method to do a display.

var theResult = myFunction( 4 );
console.log( theResult );

OR directly

console.log( myFunction( 4 ) );

Oh...My...Gosh.... wow. Thanks so much!

la sintaxi esta bien... el problema es que debes de copiar los mensajes tal cual te dice el problema.... por ejemple los signos de exclamación(!¡) tuve el mismo problema... copia y pega el comentario tal cual manda el problema.. suerte :smiley:
