Javascript Object对象转Map

1. Object对象

const data = {
	"banana": [
		{
			"color": "yellow",
			"count": 2
		},
		{
			"color": "green",
			"count": 3
		},
		{
			"color": "black",
			"count": 12
		}
	],
	"apple": [
		{
			"color": "yellow",
			"count": 3
		},
		{
			"color": "green",
			"count": 31
		},
		{
			"color": "red",
			"count": 20
		}
	]
}

2. 转Map

// 方法一
const map = new Map(Object.keys(data).map(key=>[key, data[key]]))
// 方法二
const map = new Map(Object.entries(data).map(([key, value]) => [key, value]));
