I have an argument that passes me a 2D array and I want to get the numbers from that array and put them on a normal array.
The argument passed to me = ([1, 3, 2], [5, 2, 1, 4], [2, 1]) What I want to do = [1, 3, 2, 5, 2, 1, 4, 2, 1]
Thanks in advance, I think I'm having a brain fart over here!
You can use the flat method of Array!
const arr = [[1, 2, 3], [4, 5, 6]]
console.log(arr.flat())
// [1, 2, 3, 4, 5, 6]
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/flat
Iterate the array and add all data in new array with concat() method.
var arr = [[1, 3, 2], [5, 2, 1, 4], [2, 1]];
var newArr = [];
for(var i = 0; i < arr.length; i++)
{
newArr = newArr.concat(arr[i]);
}
console.log(newArr);
You can use array flat method to convert 2d array to 1d array
const arr = [
[1,2,3],
[4,5,6]
].flat(1); //flat(depth:Number)
console.log(arr);
// [1,2,3,4,5,6]
