javascript - 比较两个数组对象数据并作为一个对象合并到 javascript 中的数组中？

Question

我的数组:

const create = [{"month":"Jan","createCount":"4"},{"month":"Feb","createCount":"5"}];

const close = [{"month":"Jan","closeCount":"3"},{"month":"Feb","closeCount":"5"}];

我需要将数组对象合并到比较月份字段。

我想要这样的结果...

const data = [{"month":"Jan","createCount":"4","closeCount":"3"},{"month":"Feb","createCount":"5","closeCount":"5"}];

我试过这段代码:

const data = [...create, ...close];

但这只是合并两个数组数据。

请给我任何解决方案!

您可以使用 .map() 和 Object.assign() 方法:

const create = [{"month":"Jan","createCount":"4"}, {"month":"Feb","createCount":"5"}],
      close = [{"month":"Jan","closeCount":"3"}, {"month":"Feb","closeCount":"5"}];

const result = create.map(
    o => Object.assign({}, o, close.find(({month}) => month === o.month))
);

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
