JavaScript For 循环内的 If 语句

Question

我正在尝试返回 16 岁或以上人员的新姓名数组。

const examplePeopleArray = [
        { name: 'John', age: 14 },
        { name: 'Joey', age: 16 },
        { name: 'Jane', age: 18 }
      ];

function getNamesOfLegalDrivers(people) {
    let legalDriver = []
        for (let i = 0; i > People.length; i++){
        if ( i >= 1){
    legalDriver += people.name.push(i)
        } else {
        legalDriver += i
    }
        }
    return legalDriver;
    }
    console.log(getNamesOfLegalDrivers(examplePeopleArray))

Answer 1

只需使用 array.filter 和 array.map，这是代码片段:

const examplePeopleArray = [
        { name: 'John', age: 14 },
        { name: 'Joey', age: 16 },
        { name: 'Jane', age: 18 }
      ];

let legalDriverNames = examplePeopleArray.filter(p => p.age >=16).map(p => p.name);

console.log(legalDriverNames);
