通过JavaScript中的特定属性过滤对象数组？
使用的概念map()与三元运算符一起（？）。以下是我们的对象数组-
let firstCustomerDetails =
[
{firstName: 'John', amount: 100},
{firstName: 'David', amount: 50},
{firstName: 'Bob', amount: 80}
];
let secondCustomerDetails =
[
{firstName: 'John', amount: 400},
{firstName: 'David', amount: 70},
{firstName: 'Bob', amount: 40}
];假设我们需要按数量属性过滤对象数组。考虑数量最多的一个。
示例
let firstCustomerDetails =
[
{firstName: 'John', amount: 100},
{firstName: 'David', amount: 50},
{firstName: 'Bob', amount: 80}
];
let secondCustomerDetails =
[
{firstName: 'John', amount: 400},
{firstName: 'David', amount: 70},
{firstName: 'Bob', amount: 40}
];
var output = firstCustomerDetails.map((key, position) =>
key.amount > secondCustomerDetails[position].amount ? key :
secondCustomerDetails[position]
);
console.log(output);要运行上述程序，您需要使用以下命令-
node fileName.js.
在这里，我的文件名为demo83.js。
输出结果
这将产生以下输出-
PS C:\Users\Amit\JavaScript-code> node demo83.js
[
{ firstName: 'John', amount: 400 },
{ firstName: 'David', amount: 70 },
{ firstName: 'Bob', amount: 80 }
]
