How to filter objects based on given condition in JavaScript?-CodePudding

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.

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);```

output like this:-
```['Blake Hodges']```

CodePudding user response：

Maybe you want this?

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:

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)

CodePudding user response：

You can achieve this by using Array.filter() method along with Array.every() to test whether all elements in the array pass the test implemented by the provided function. It returns a Boolean value.

Working Demo :

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

let res = candidatesList.filter((obj) => {
    return obj.points.every((item) => item > 75)
});

console.log(res);
