fetch('https://raw.githubusercontent.com/internet5/smart-array-to-tree/master/example/data.json').then(function(response) {
return response.json();
}).then(function(data) {
//start time
console.log(new Date());
//transform
let tree = smartArrayToTree(data, { id:'regionId', pid:'parentId', firstPid:null });
//end time
console.log(new Date());
}).catch(function(e) {
console.log(e);
