How to return only the Date from a SQL Server DateTime datatype.

Javascript - lodash or native array functions get first item

I have the following data

data: [
    [200, 3],
    [400, 4],
    [2344, 8],
    [34543, 2],
];

What I am trying to do with lodash or native filter/map functions is to create 2 arrays.

array1 = [200, 400, 2344, 34543];
array2 = [3, 4, 8, 2];

I have tried map, filter and lodash first with no luck.
