Usage

Initialize

let treeB = new SuminTree('B').add('D').add('F').add('G');
let treeC = new SuminTree('C').add('H').add('I');
let tree = new SuminTree('A').add(treeB).add(treeC);
let _tree = SuminTree.obj2tree({
    value: 'A', children: [
        { value: 'B', children: [
            { value: 'D', children: [] },
            { value: 'F', children: [] },
            { value: 'G', children: [] }
        ] },
        { value: 'C', children: [
            { value: 'H', children: [] },
            { value: 'I', children: [] }
        ] }
    ]
});

// Identical content
assert.deepEqual(tree, _tree);

_tree = new SuminTree(tree);
// A different instance
assert.notEqual(tree, _tree);
// Identical content
assert.deepEqual(tree, _tree);
