Special Note:

1. You require array of objects for nth level tree
2. Require Key & Value which consists children's for node

import {findObjectFromTree} from "nth-level-search-node";

let treeData = {"name":"root","data":[{"id":1,"name":"Level 1","data":[{"id":11,"name":"Level 1.1","data":[{"id":111,"name":"Level 1.1.1","data":[]}]},{"id":12,"name":"Level 1.2","data":[{"id":121,"name":"Level 1.2.1","data":[]}]}]},{"id":2,"name":"Level 2","data":[{"id":21,"name":"Level 2.1","data":[{"id":211,"name":"Level 2.1.1","data":[]}]},{"id":22,"name":"Level 2.2","data":[{"id":221,"name":"Level 2.2.1","data":[]}]}]}]};
let findArrList = [11, 221];
let uniqueKey = "id";

function  findObjectFromJson(){
	let resultData =  findObjectFromTree({
		"treeObj": treeData,
		"findArray": findArrList,
		"uniqueKey" : uniqueKey
	});
    if(resultData.length == 0){
        console.log("No Objects are found.");
    }
    else{
        console.log("Result Data ", resultData);     
    }	   
}

// Result Result Data
