[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 could join and split the string.

console.log(["12,3", "3", "5", "66,22"].join().split(','));

Answer 2

I believe that you miss one 3 element in your desired output, if so - try following solution:

var arr = ["12,3","3","5","66,22"],
    res = [].concat(...arr.map(v => v.split(',')));
    
    console.log(res);

Answer 3

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(","))]
}

Answer 4

To throw another onto the pile:

   a = Array.from([...new Set(["12,3", "3", "5", "66,22"].flatMap(x=>x.split(",")))])
console.log(a)

if uniqueness wasn't required, then just doing flatMap to the input would be enough
