将值分配给JavaScript中的计算属性？
以下是我们的目标-
const customerDetails=[
{customerFirstName: "David"},
{customerLastName: "Miller"},
{customerCountryName: "US"},
{customerAge: "29"},
{isMarried: false},
{customerCollegeName: null}
];让我们使用slice()和将值分配给计算属性map()。
示例
const customerDetails=[
{customerFirstName: "David"},
{customerLastName: "Miller"},
{customerCountryName: "US"},
{customerAge: "29"},
{isMarried: false},
{customerCollegeName: null}
];
const newCustomerDetails =
customerDetails.slice(2,4).concat(customerDetails[5]).map(obj=>({
propertyKey: Object.keys(obj)[0],
propertyValue: Object.values(obj)[0]
}));
console.log(newCustomerDetails);要运行以上程序，您需要使用以下命令-
node fileName.js.
在这里，我的文件名为demo135.js。
输出结果
这将产生以下输出-
PS C:\Users\Amit\JavaScript-code> node demo135.js
[
{ propertyKey: 'customerCountryName', propertyValue: 'US' },
{ propertyKey: 'customerAge', propertyValue: '29' },
{ propertyKey: 'customerCollegeName', propertyValue: null }
