flatting and sorting nested arrays In javascript nodejs

Question

I have an array that outputs numerous arrays, but if some of the codes are the same, they all output in the same array. How do I separate them?

[
[ [ '0011', 6, 96, '2021-08-16' ], [ '0011', 2, 4, '2021-08-17' ] ],
  [ [ '0032', 20, 26, '2021-08-16' ] ],
  [ [ '0098', 6, 246, '2021-08-16' ], [ '0098', 0, 0, '2021-08-17' ] ],
  [ [ '0093', 2, 30, '2021-08-16' ] ],
  [ [ '0051', 32, 229, '2021-08-16' ] ],
  [ [ '0053', 27, 63, '2021-08-16' ], [ '0053', 2, 38, '2021-08-17' ] ],
  [ [ '0022', 4, 2, '2021-08-16' ], [ '0022', 6, 12, '2021-08-17' ] ],
  [ [ '0067', 2, 144, '2021-08-16' ] ],
  [ [ '0166', 4, 102, '2021-08-16' ] ],
  [ [ '0015', 4, 96, '2021-08-16' ] ],
]

How do I retrieve the values that have two or more values in their array and put them in so that each one is distinct within the array, if that makes sense?

[
[ [ '0011', 6, 96, '2021-08-16' ]], 
[[ '0011', 2, 4, '2021-08-17' ] ],
  [ [ '0032', 20, 26, '2021-08-16' ] ],
  [ [ '0098', 6, 246, '2021-08-16' ],
[ [ '0098', 0, 0, '2021-08-17' ] ],
  [ [ '0093', 2, 30, '2021-08-16' ] ],
  [ [ '0051', 32, 229, '2021-08-16' ] ],
  [ [ '0053', 27, 63, '2021-08-16' ]],
  [ [ '0053', 2, 38, '2021-08-17' ] ],
  [ [ '0022', 4, 2, '2021-08-16' ]], 
  [ [ '0022', 6, 12, '2021-08-17' ] ],
  [ [ '0067', 2, 144, '2021-08-16' ] ],
  [ [ '0166', 4, 102, '2021-08-16' ] ],
  [ [ '0015', 4, 96, '2021-08-16' ] ],
]

Or

[
[  '0011', 6, 96, '2021-08-16' ], 
[ '0011', 2, 4, '2021-08-17' ],
  [  '0032', 20, 26, '2021-08-16'  ],
  [  '0098', 6, 246, '2021-08-16' ],
[  '0098', 0, 0, '2021-08-17' ],
  [  '0093', 2, 30, '2021-08-16'  ],
  [ '0051', 32, 229, '2021-08-16'  ],
  [ '0053', 27, 63, '2021-08-16' ],
  [ '0053', 2, 38, '2021-08-17' ],
  [ '0022', 4, 2, '2021-08-16' ], 
  [  '0022', 6, 12, '2021-08-17'  ],
  [  '0067', 2, 144, '2021-08-16' ],
  [ '0166', 4, 102, '2021-08-16'  ],
  [ '0015', 4, 96, '2021-08-16'  ],
]

I tried flatten, but it only added the arrays in the same array together, which isn't what I wanted.

Answer 1

Try this:

let myarray = [
 [ [ '0011', 6, 96, '2021-08-16' ], [ '0011', 2, 4, '2021-08-17' ] ],
 [ [ '0032', 20, 26, '2021-08-16' ] ],
 [ [ '0098', 6, 246, '2021-08-16' ], [ '0098', 0, 0, '2021-08-17' ] ],
 [ [ '0093', 2, 30, '2021-08-16' ] ],
 [ [ '0051', 32, 229, '2021-08-16' ] ],
 [ [ '0053', 27, 63, '2021-08-16' ], [ '0053', 2, 38, '2021-08-17' ] ],
 [ [ '0022', 4, 2, '2021-08-16' ], [ '0022', 6, 12, '2021-08-17' ] ],
 [ [ '0067', 2, 144, '2021-08-16' ] ],
 [ [ '0166', 4, 102, '2021-08-16' ] ],
 [ [ '0015', 4, 96, '2021-08-16' ] ],
 ];




  let cleanArry = [];

  myarray.forEach(item=>{
  item.forEach(nItem=>{
    cleanArry.push(nItem)
  })
  })
  
  //this is the array that you want 
  console.log(cleanArry);
