Missing brace? And troubleshooting function syntax?

#1

I clicked on “Get Solution” then copy/pasted this:

const finalGrade = (midterm, final, homework) => {
    if ((midterm < 0 || midterm > 100) || (final < 0 || final > 100) || (homework < 0 || homework > 100)) {
        return 'You have entered an invalid grade.'
    }

But I get helper error “SyntaxError: Unexpected token )”

Please how can the solution code be wrong, and how do I fix it please?

Not able to reproduce this error. Did find a missing brace, though.

#3

Need to see the rest of your code. You may have an extra ) somewhere else.

#4

where please is the missing brace? I see an opening brace and a closing brace so do not understand what is missing. I have both { and }.

#5

There is no more code. I only pasted in my lesson what I pasted here in this forum. Thank you.

#6

We can see two opening braces but only one closing brace.

#7

I removed the opening brace after the if statement and do not get error messages now. How do I report a mistake in the codecademy solution? Mistakes in solutions make learning very difficult:(

#8

Moving along in the solution I’m also finding difficulty here:

let average = (midterm + final + homework) / 3
THE CODE ABOVE IS FROM THE SOLUTION PROVIDED. When I paste it in main.js and Run, I get errors. So I changed it to this:
let average = ‘(midterm + final + homework) / 3’;
I don’t get errors when I run that but I’m not sure if it is correct. Can you confirm the solution for me please?

#9

Moving along in the exercise, I’m trying to test my code by calling the function but it’s not working, please find my error? I’m testing my code like this:

console.log(finalGrade(50, 70, 5));

and below is my code in its entirety:

const finalGrade = (midterm, final, homework) => {
if ((midterm < 0 || midterm > 100) || (final < 0 || final > 100) || (homework < 0 || homework > 100))
return ‘You have entered an invalid grade.’
}

let average = ‘(midterm + final + homework) / 3’;
if(average<60){
return ‘F’
} else if(average<70){
return ‘D’
} else if(average<80){
return ‘C’
} else if(average<90){
return ‘B’
} else {
return ‘A’
};

console.log(finalGrade(50, 70, 5));

THANK YOU!

You need the { after the if(condition) statement. The code to run when the if(condition) evaluates to true should be in a code block encased in {}:

if(a + b === c) {
  //code to execute if true
} else {
  //code to execute if false
}

When @mtf said you were missing a }, he was referring to the one at the very end of the finalGrade function:

const finalGrade = (parameters) => {
  //function code goes here for example:
  if(a + b === c) {
    //code to execute if true
  } else {
    //code to execute if false
  }
  return something;

if ((midterm < 0 || midterm > 100) || (final < 0 || final > 100) || (homework < 0 || homework > 100)) `{` 
return ‘You have entered an invalid grade.’
}

You are missing the open curly brace following the if(condition).

let average = `‘`(midterm + final + homework) / 3`’`;

The value assigned to the average variable should not be encased in quotes. You are later comparing it to numbers: average<60 and so on. You need average to be a number not a string.

return ‘F’`;`
return ‘D’`;`
return ‘C’`;`
return ‘B’`;`
return ‘A’`;`

These statements should end with a ;

if(average<60){
return ‘F’
} else if(average<70){
return ‘D’
} else if(average<80){
return ‘C’
} else if(average<90){
return ‘B’
} else {
return ‘A’
}; //This curly brace closes your last else code block.
`}` //You need this one to close the function. This is the one missing from the beginning.

Good luck! Hope this helps!
