Question: I'm new to this community and just started programming I couldn't find anything about this topic can anyone please solve this.
I need to filter names who's each points in array above 75.
i have tried this and unable iterate over an array.

```js
const candidatesList = [{'name':'Blake Hodges', 'points':[76,98,88,84]},{'name':'James Anderson', 'points':[0,98,12,13]}]

const arrayOfSelecetedCandidates=[]
  for(let object of candidatesList){
      if (candidatesList.every(candidatesList.points>75)){
         arrayOfSelecetedCandidates.push(candidatesList.name)
      }
  }
  console.log(arrayOfSelecetedCandidates);
```

Answer: 
Maybe you want this?

```js
const candidatesList = [{'name':'Blake Hodges', 'points':[76,98,88,84]},{'name':'James Anderson', 'points':[0,98,12,13]}]

const arrayOfSelecetedCandidates=[]
  for(let object of candidatesList){
      if (object.points.every(i=>i>75))
         arrayOfSelecetedCandidates.push(object.name)
  }
  console.log(arrayOfSelecetedCandidates);
```

But as @Dai pointed out filter is always better if you want to test an array and return item that pass the test:

```js
const candidatesList = [{'name':'Blake Hodges', 'points':[76,98,88,84]},{'name':'James Anderson', 'points':[0,98,12,13]}]

const arrayOfSelecetedCandidates=candidatesList.filter(i=>i.points.every(y=>y>75))
console.log(arrayOfSelecetedCandidates)
```

Looking at the content of OP, I believe that's incorrect. It would make more sense if the desired output would be only the objects (aka candidates) that have an ***average of points*** at or above 75 not a total of 75 (although not explained very well). So the plan of attack would be:

* Get each of the candidates with a `for...of` loop:

```
for (const candidate of candidates) {...

```
* Get each of the candidate's points (`candidate.points`) and get their sums using `.reduce()` (note: the return goes to a new property called `.total`). Then take that total and divide by the number of grades found in points array (it's `candidate.points.length` = 4):

```
candidate.total = candidate.points.reduce((sum, cur) => sum + cur, 0);
candidate.gpa = Math.floor(candidate.total / candidate.points.length);

```
* Once `candidate.gpa` is established, `.filter()` will determine if it is equal to or greater than 75.

```
return candidates.filter(candidate => candidate.gpa >= 75);

```

```js
const candidates = [{
  'name': 'Blake Hodges',
  'points': [76, 98, 88, 84]
}, {
  'name': 'James Anderson',
  'points': [0, 98, 12, 13]
}, {
  'name': 'Zer0 0ne',
  'points': [100, 88, 91, 84]
}, {
  'name': 'Ronald McDonald',
  'points': [72, 51, 8, 89]
}];

const selected = candidates => {
  for (const candidate of candidates) {
    candidate.total = candidate.points.reduce((sum, cur) => sum + cur, 0);
    candidate.gpa = Math.floor(candidate.total / candidate.points.length);
  }
  return candidates.filter(candidate => candidate.gpa >= 75);
};

console.log(selected(candidates));
```
