1、示例代码

let arr = [
	
		id: 1,
		name: "一级1",
		children: [
			 id: 2, name: "二级1", children: [] ,
			
				id: 3,
				name: "二级2",
				children: [ id: 4, name: "三级1", children: [] ],
			,
		],
	,
	
		id: 5,
		name: "一级2",
		children: [],
	,
];

function flatten(arr) 
	return arr.reduce((result, item) => 
		return result.concat(item, Array.isArray(item.children) ? flatten(item.children) : []);
	, []);


console.log(flatten(arr));
