javascript - Save the edited tree as a json object in the original format -

let data = { "name": "root", "children": [{     "name": "analytics",     "children": [{         "name": "cluster",         "children": [{             "name": "agglomerativecluster",             "size": 3938         }]     }, {         "name": "graph",         "children": [{             "name": "betweennesscentrality",             "size": 3534         }]     }, {         "name": "optimization",         "children": [{             "name": "aspectratiobanker",             "size": 7074         }]     }] }] };  let child1 = { "name": "flex", "children": [{     "name": "flarevis",     "size": 4116 }] };  let tree = new treemodel(); let root = tree.parse(data); //# add child let tempchild1 = tree.parse(child1); //# add child @ given index root.addchildatindex(tempchild1, 0); console.log(root); 

using library: http://jnuno.com/tree-model-js/ tree manipulation. so, how possible data library in original format after addition or deletion.

after above operation, how can modified object library?    data = { "name": "root", "children": [{     "name": "analytics",     "children": [{         "name": "cluster",         "children": [{             "name": "agglomerativecluster",             "size": 3938         }]     }, {         "name": "graph",         "children": [{             "name": "betweennesscentrality",             "size": 3534         }]     }, {         "name": "optimization",         "children": [{             "name": "aspectratiobanker",             "size": 7074         }]     }] }, {     "name": "flex",     "children": [{         "name": "flarevis",         "size": 4116     }] }] } 

is there way library can this, or there efficient way convert desired format, original format.

json.stringify(root.model); 

solves problem, found answer @ transforming tree json using tree-model-js , cloning js treemodel tree

thank much.
