Permuter

It generates all possible combinations receiving a set of possible attributes and values choosing one value per attribute at the time.

Example input:

  const options = {
    optionA: ['A-value-1', 'A-value-2'],
    optionB: ['B-value-1', 'B-value-2', 'B-value-3'],
    optionC: ['C-value-1']
  }

Example output (all possible combinations):

  [
     {
        "optionA": "A-value-1",
        "optionB": "B-value-1",
        "optionC": "C-value-1"
     },
     {
        "optionA": "A-value-1",
        "optionB": "B-value-2",
        "optionC": "C-value-1"
     },
     {
        "optionA": "A-value-1",
        "optionB": "B-value-3",
        "optionC": "C-value-1"
     },
     {
        "optionA": "A-value-2",
        "optionB": "B-value-1",
        "optionC": "C-value-1"
     },
     {
        "optionA": "A-value-2",
        "optionB": "B-value-2",
        "optionC": "C-value-1"
     },
     {
        "optionA": "A-value-2",

        "optionC": "C-value-1"
