Script Preparation code:

  // I'm a steamroller, baby
  var a = [];
  function roll(arr){
    
    if(!Array.isArray(arr)) {
      a.push(arr);
    }
    
  else {
    arr.forEach(x=>{
    roll(x);
    });
  }
  }
  
  roll(arr);
  return a;
}


var result = []

function steamrollArraySomeone(arr) {
  for(var i=0; i < arr.length; i++)
    Array.isArray(arr[i]) ? steamrollArraySomeone(arr[i]) : result.push(arr[i])
  return result;
}

  for (var i = 0; i<=arr.length; i++){
  if (Array.isArray(arr[i]) === true){
    arr = arr.reduce( (a, b) => a.concat(b), []);
    i=0;
  }
