getTree(data) { const backArr = JSON.parse(JSON.stringify(data)).reverse() let childArr = [] let treeArr = [] function recursion(arr1) { if (arr1.length === 1) { arr1[0].children = childArr treeArr = JSON.parse(JSON.stringify(arr1)) } else...
randomString() { let arrSize = 0 let code = '' const arrSet = new Set() while (arrSize < 1000) { code = Math.floor(Math.random() * 1000000) + '' code.length === 6...
