如何将javascript对象转换为键/值数组
问题描述：
给定一个JavaScript对象，如何将其转换为对象数组（每个对象都有键，值）？
Given a JavaScript object, how can I convert it into an array of objects (each with key, value)?
示例：
var data = { firstName: 'John', lastName: 'Doe', email: 'john.doe@gmail.com' }
结果如：
[
{ key: 'firstName', value: 'John' },
{ key: 'lastName', value: 'Doe' },
{ key: 'email', value: 'john.doe@gmail.com' }
]
答
var data = { firstName: 'John', lastName: 'Doe', email: 'john.doe@gmail.com' }
var output = Object.entries(data).map(([key, value]) => ({key,value}));
console.log(output);
