API

tree.add() - add item in tree

tree.add(data, parent, addAllByOne)

The first argument is the data that the tree node will store The second argument is the parent node that will store the new node

import Tree from "tree-data-structure";

const tree = new Tree('root')

tree.add('child', tree.root)

/*
 output tree root node

 {
	data: 'root',
	children: [{
		data: 'child',
		children: []
	}]
 }
*/

Third argument is optional. If you pass an array of data as the first argument and pass true as the third argument, each element of the array will be added as a separate node

import Tree from "tree-data-structure";

const tree = new Tree('root')

tree.add(['one', 'two', 'three'], tree.root, true)

/*
 output tree root node

 {
	data: 'root',
	children: [
		{
			data: 'one',
			children: []
		},
		{
			data: 'two',
			children: []
		},
		{
			data: 'three',
			children: []
		}
	]
 }
*/

import Tree from "tree-data-structure";

const tree = new Tree('root')

tree.add({ one: 1, two: 2, three: 3 }, tree.root)
