@Favna thank you ,i solve the bug.it is saved my time.

`'10000000000'.replace(/(?!^)(?=(\d{3})+$)/g,'.')`

parseInt接受两个参数~1,0为十进制，2,1不存在，3,2不存在。 因此，1，nan,nan

var timer = null; var a = function(t){ console.log(new Date().valueOf()) timer= setTimeout(a,t) } a.close=function(){ clearTimeout(timer) } a(1000) // 模拟一秒一次 a.close() // 关闭 // 区别

``` test=(arr) => { let [_str, str] = ['', arr.toString()] const match = [...str.matchAll(/(^0,)|(,0)/g)] _str = str.replace(/,0/g, '').replace(/^0,/, '') + ',0'.repeat(match.length) return _str.split(',') } ``` 哈哈哈，这样算不算离题了啊 求大佬斧正

` ['黄','红','蓝'].map((o)=>o.repeat([...'红蓝蓝黄红黄蓝红红黄红'.matchAll(o)].length)).join('') ` 一行代码嘻嘻

提高diff算法性能，且减少对比出错风险~虽然不太可能出错。
