Score 70+ (ES6)

Question

Instructions are to use the “for...of...” loop but I am so confused by that that I was trying to solve another way and I still can’t seem to get it right. Any help on what is wrong with my code below would be helpful!

CHALLENGE:
// Students need to score at least 70 points to pass an exam. The given program declares an array with results.
Write a program to count and output to the console the number of students who pass the exam.

let scores = [68,95,54,84,77,75,63,74,69,80,71,63]

//your code goes here

/* // I started with this and then switched to what I’m more familiar with.
for (let a of scores){
return(a);
*/

for (let x = 0; x >= scores.length) {
if (scores[x] < 70) {
continue;
}

if (scores[x] >= 70) {
return scores[x];
}

x += 1;
}

}

console.log(x);

Answer 1

KfMand08, look at the code. I can suggest also second way to solve it with filter method. Hope it helps you.

Answer 4

//This is how i made it out
/*We Are given an array of numbers so let's create an array out the given array with values greaterhan or equal to 70*/
let scores = [68,95,54,84,77,75,63,74,69,80,71,63]

let num = [];

for(let scoreAbove of scores){

if(scoreAbove >= 70){
num.push(scores[scoreAbove]);
}
}
console.log(num.length);

Answer 5

let list = [68, 95, 54, 84, 77, 75, 63, 74, 69, 80, 71, 63];
var passed = 0;
var failed = 0;
for (let i = 0; i < list.length; i++) {
if (list[i] >= 70) {
passed += 1;
} else {
failed += 1;
}
}
console.log(`passed: ${passed} \nfailed: ${failed}`);

Answer 6

let scores = [68,95,54,84,77,75,63,74,69,80,71,63]

let passingScores = 0

for (let theNumbersINtheArray of scores) {
if (theNumbersINtheArray >= 70) // do the code in curly brackets
{passingScores++; // increment passingScores by 1
}
}
console.log(passingScores)

Answer 7

let scores = [68,95,54,84,77,75,63,74,69,80,71,63]

//your code goes here
//create array to save the marks of students who passed
var studentsPassed = new Array();

for(let pass of scores){
if (pass >= 70){
//add scores of the passed students to the array
studentsPassed.push(pass);
}
}
//output the number of students who passed
console.log(studentsPassed.length);

Answer 8

let scores = [68, 95, 54, 84, 77, 75, 63, 74, 69, 80, 71, 63];

let newArr = [];

for (i = 0; i < scores.length; i++) {
if (scores[i] >= 70) {
newArr.push(scores[i]);
}
}
console.log(newArr.length);

Answer 9

let scores = [68,95,54,84,77,75,63,74,69,80,71,63]
let i = 0;

for(let result of scores){
if(result > 70){
i++;
}
}
console.log(i);
