javascript - 使用 map 将二维字符串数组转换为拆分数值数组

Question

我有一个这样的数组:

var array=[
    ['0000'],
    ['0000']
]

我想得到这样的结果:

var result=[
    [0,0,0,0],
    [0,0,0,0]
]

javascript map 这怎么可能？

我的带有愚蠢 for 循环的解决方案如下所示:

var array=[
    ['0000'],
    ['0000']
]

var new_array=[]

for (var i=0; i<array.length;i++) {
  new_array.push((array[i].toString().split('').map(Number)))
}
console.log(new_array)

Edit 1.0 How to get the same result if my array looks like this:

['0000','0000','0000']

Edit 2.0 Ok last edit - How to turn around the process? So getting from
[[0,0,0,0], [0,0,0,0]] -- > [['0000'], ['0000']]

EDIT 3 -- OK found the solution for Edit 2 on my own:

array.map(a => [a.join('')])

感谢您的帮助。

Answer 1

To handle the following scenario...

var arrays=[
  ['0000', '0000', '0000'],
  ['0000', '0000', '0000'],
  ['0000', '0000', '0000'],
  // etc...
];

arrays.map(ary => ary.reduce((ary, stg) => ary.concat(stg.split('').map(Number)), []));
// => [[0,0,0,0,0,0,0,0,0,0,0,0], [0,0,0, etc...], etc...];

A little shorter based on answer from @Josh from Qaribou

arrays.map(ary => ary.reduce((ary, stg) => ary.concat(Array.from(stg, Number)), []));
