How to split two data in one array element

Question

I have an array and want to split two data that contain in one array element.

Here is the code :

const array = ["1 Boston 4 11", "2 Florida 6 14\n3 Texas 5 12", "4 California 7 13"];

array.map(x => {
  return (
    console.log(x.split(" "))
  )
});

array[1] contain two data : 2 Florida 6 14 and 3 Texas 5 12. I need to split array[1] to two different arrays with each data.

Result i expect :

[
  "1",
  "Boston",
  "4",
  "11"
]
[
  "2",
  "Florida",
  "6",
  "14"
]
[
  "3",
  "Texas",
  "5",
  "12"
]
[
  "4",
  "California",
  "7",
  "13"
]

Anyone can please help me to solve that?

First split for each line break and then for each whitespace

const array = ["1 Boston 4 11", "2 Florida 6 14\n3 Texas 5 12", "4 California 7 13"];
console.log(array.flatMap(x => x.split("\n")).map(x => x.split(" ")));

As kemicofa explained not all browsers support Array#flatMap. The recommended alternative for flatMap is a combination of Array#reduce and Array#concat:

const array = ["1 Boston 4 11", "2 Florida 6 14\n3 Texas 5 12", "4 California 7 13"];
console.log(array.reduce((acc, x) => acc.concat(x.split("\n")), []).map(x => x.split(" ")));

Array#flatMap is not cross-compatible on IE or Edge. Here is an alternative with Array#join and String#split

const data = ["1 Boston 4 11", "2 Florida 6 14\n3 Texas 5 12", "4 California 7 13"];

const res = data.join("\n").split("\n").map(item=>item.split(" "));

console.log(res);
