验证数组的所有对象中的属性值是否为假，并从数组的前三个最大对象中选择属性的值

Question

我有一组具有属性的对象

let array = [{value: "None", selected: false, name: "None"},
{value: "sample utternace", selected: false, name: "sample utternace"},
{value: "sample", selected: false, name: "sample"}]

如果所有对象的“选择”属性为“假”，我需要根据这些对象数组进行验证。
如果是，那么我需要为前三个最大值选择属性“值”的值，如果“None”值除外。
如果数组大小小于属性“值”的最小 2 个值，则应选择属性“值”的最大 3 个值应将其推送到数组

尝试过：

let newArray = [];
let sendValues: boolean;
for (let i = 0; i < array.length; i++) { // validate if all no value selected
    if (array[i].selected === true) {
       sendValues = true;
       break;
       } else {
         break;
       } 
     }                         
      if (sendValues) {                  
                    
            } else {
                for (let i = 0; i < 4; i++) {
                    if (array[i].value === "None") {
                        newArray.push();
                    } else {
                        newArray.push(array[i].value);
                    }
                }           
            }   
        }

第 1 部分：

let array = [{value: "None", selected: false, name: "None"},
{value: "sample utternace", selected: false, name: "sample utternace"},
{value: "sample", selected: false, name: "sample"}]

console.log(array.every(({selected}) => !selected)); // test all have false

第 2 部分

let array = [{value: "None", selected: false, name: "None"},
{value: "sample utternace", selected: false, name: "sample utternace"},
{value: "sample", selected: false, name: "sample"}]

if (array.every(({selected}) => !selected) ) {
  console.log(array.filter( ({value}) => value !="None")); // filter on value=None
}

第 3 部分

let array = [{value: "None", selected: false, name: "None"},
{value: "sample utterance1", selected: false, name: "sample utterance1"},
{value: "sample utterance2", selected: false, name: "sample utterance2"},
{value: "sample utterance3", selected: false, name: "sample utterance3"},
{value: "sample", selected: false, name: "sample"}]

const getSample = array => {
  let arr = [];
  if (array.every(({ selected }) => !selected)) {
    arr = array.filter( ({ value }) => value != "None")
    if (arr.length >= 3) return arr.slice(0, 3)
  }
  return []; // or some other size
};

console.log(getSample(array))
