Question

drunk_ppl = [
    {name: 'Mark', age: 20,  alcohol_type: 'Whiskey'},
    {name: 'Jon',  age: 25,  alcohol_type: 'Rum'},
    {name: 'April',  age: 22,  alcohol_type: 'Gin'},
    {name: 'Simon',  age: 50,  alcohol_type: 'Vodka'}
];

smoker = [
    {name: 'Mark', cig_a_day: 20, brand: 'Marlboro'},
    {name: 'Jon', cig_a_day: 15, brand: 'Camel'},
    {name: 'April', cig_a_day: 12, brand: 'Newport'},
    {name: 'Simon', cig_a_day: 5, brand: 'Dunhill'}
];

var drunkard = []; //creating empty array
for(var i = 0; i < drunk_ppl.length; i++) {
    drunkard[i] = drunk_ppl[i].name;
}

需要有关此代码段的帮助。

基本上我想要这样的东西：

drunk_ppl中的人在drunkard

中添加人名来自drunkard数组的

取一个名称并使用该名称从smoker数组中查找cigarrette的品牌。

如果在吸烟者阵列中找不到匹配项，则不执行任何操作

Answer 1

检查这个片段，你可以将它包装在一个函数上，你很高兴

smoker.filter(x=>x.name==="Mark").forEach(x=>console.log(x.brand));

首先按您想要的名称筛选吸烟者阵列
然后您打印（或在其他地方添加）按名称对象过滤的品牌属性

Answer 2

drunk_ppl.map(ele=>ele.name). // return array of name from drunk_ppl
forEach(function(ele, index){  //loop through array of names
console.log(smoker.find(element=> element.name === ele).brand) /*find brands for name*/
})

编码采访数组
