如何在NodeJs中将字符串转换为数组

我有这个字符串：

    var d = [
    '[(not set),20200409,103,0.0]',
    '[(not set),20200410,112,0.0]',
    '[(not set),20200411,56,0.0]',
    '[(not set),20200412,58,0.0]',
    '[(not set),20200413,108,0.0]',
    '[(not set),20200414,91,0.0]'];

但是我希望通过转换字符串d来获得这种类型的数组处理后看起来应该像。

    var processd_array = [
     ['(not set)',20200409,103,0.0],
     ['(not set)',20200410,112,0.0],
     ['(not set)',20200411,56,0.0],
     ['(not set)',20200412,58,0.0],
     ['(not set)',20200413,108,0.0],
     ['(not set)',20200414,91,0.0] ];

如何在Node.js中做到这一点？

首先，让我们将d数组中的每个元素分割成碎片。

var d= [
  '[(not set),20200409,103,0.0]',
  '[(not set),20200410,112,0.0]',
  '[(not set),20200411,56,0.0]',
  '[(not set),20200412,58,0.0]',
  '[(not set),20200413,108,0.0]',
  '[(not set),20200414,91,0.0]'];
 
const result = d.map(item => item.split(','));

console.log(result);
