```javascript function transTree(arr) { let map = arr.reduce((acc, item) => { acc[item.id] = item; item.children = []; return acc }, {}) for (const key in map) { if (map.hasOwnProperty(key)) {...
可以手动跟“this”指定类型，如下： ```ts interface Data { numA: number numB: number get sum(): number } update: action(function(this: Data) { const sum = this.sum this.numA = this.numB this.numB = sum }) ```
越来越离谱了
