[removed] how to map array and split string content to new cell

Question

Which code should I use on js to map an array with spliting cells yet not reapeating [\"12,3\",\"3\",\"5\",\"66,22\"] into [\"12\",\"3\",\"5\",\"66\",\"22\"]<

Answer 1

You can use this ES6 way to get the desired output

x = ["12,3","3","5","66,22"];
y = [];
for (i of x){
  y = [...y, ...(i.split(","))]
}
