Question

Im trying to slice a matrix so that I can end up with to arrays.
So given the following matrix [[1,2],[3,4],[102,5]] is there a way to slice it so that I end up with [1,3,102] and [2,4,5] ?

Maybe its not a slice but something else?
Thanks

Try using the Array.reduce(...) method, since functional programming is cool!

function splitMatrix(matrix) {
  return matrix.reduce(function(acc, x) {
    acc[0].push(x[0]);
    acc[1].push(x[1]);
    return acc;
  }, [[],[]]);
}

splitMatrix([[1,2],[3,4],[102,5]]); // => [[1,3,102], [2,4,5]]
