Special Note:

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

import {removeObjectFromTree} from "nth-level-node-remove";

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 removeArrList = [11, 221];
let uniqueKey = "id";

function  removeObjectFromJson(){
    	 let jsonData =  removeObjectFromTree({
				"treeObj": treeData,
				"removeArray": removeArrList,
				"uniqueKey" : uniqueKey
    	 });
	 console.log("After Delete Tree == ", jsonData);
}

// Result After Delete Tree
