Review JavaScript Fundamentals by Building a Gradebook App - Step 4

Tell us what’s happening:

my if condition is right or not plz give me suggestion what condition give be given in if statement

Your code so far

function getAverage(scores) {
  let sum = 0;

  for (const score of scores) {
    sum += score;
  }

  return sum / scores.length;
}

function getGrade(score) {
  if (score === 100) {
    return "A++";
  } else if (score >= 90) {
    return "A";
  } else if (score >= 80) {
    return "B";
  } else if (score >= 70) {
    return "C";
  } else if (score >= 60) {
    return "D";
  } else {
    return "F";
  }
}

function hasPassingGrade(score) {
  return getGrade(score) !== "F";
}

function studentMsg(totalScores, studentScore) {
  let getavg = getAverage(totalScores);
  let grade = getGrade(studentScore)
  
  if(grade !== "F"){
  return  "Class average: " + getavg +" ."+" Your grade:"+ grade +". You passed the course."}
  
  else{ "Class average: " +getavg +" . Your grade: "+ grade +". You failed the course."}
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

You need correct spacing between your both return strings concatenation. Look carefully to given text in the challenge and what shows in your console.
@anamikachauhan19813

it is not working still error

I didn’t see your computer screen. Post your code.

function studentMsg(totalScores, studentScore) {
let getavg = getAverage(totalScores);
let grade = getGrade(studentScore)

if(grade !== “F”){
return “Class average:” + getavg +" .“+” Your grade:“+ grade +”. You passed the course."}

else{ “Class average:” +getavg +" .“+” Your grade:“+ grade +”. You failed the course."}
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

Why you have these variable declaration and assignment:

Instructions gave you tips:

**Use the getAverage function to get the class average.
Use the getGrade function to get the student’s grade.
Use string concatenation (+) to build the message.
Be careful with the punctuation and spaces in the message.

You need the required functions in your concatenation.

function studentMsg(totalScores, studentScore) {
let getavg = getAverage(totalScores);
let grade = getGrade(studentScore)

if(grade !== “F”){
return “Class average: " +getAverage(totalScores)+” .“+” Your grade:“+ getGrade(studentScore) +”. You passed the course."}

else{ “Class average: " +getAverage(totalScores)+” .“+” Your grade:“+ getGrade(studentScore) +”. You failed the course."}
}
console.log(studentMsg([92, 88, 12, 77, 57, 100, 67, 38, 97, 89], 37));

This is unnecessary:

And this is not defined anywhere within your code:

You need passing grade score equal to passing grade, for your if condition.
