node.js - 我们如何仅从 js 的新行中删除逗号

Question

我的量角器脚本中有一个字符串'str'，如下所示。我需要用换行符替换所有'aaaa'，并且每个新行的开头不应包含逗号。

var str="51 Cart Road #408, Missouri City, TX 77459aaaa,90 South Street, Southern Pines, NC 87-541aaaa,01 Cart Road #7708, Missouri City, TX 7659aaaa";
str=str.replace(/aaaa/g,"\n");
console.log(str);

所以我会得到结果

51 Cart Road #408, Missouri City, TX 77459
,90 South Street, Southern Pines, NC 87-541
,01 Cart Road #7708, Missouri City, TX 7659

但我的目标是得到结果

51 Cart Road #408, Missouri City, TX 77459
90 South Street, Southern Pines, NC 87-541
01 Cart Road #7708, Missouri City, TX 7659

那么我怎样才能只从新行中删除逗号。在此先感谢。
