Just experimenting with publishing a package

/* 
 !function trans2dArray(arr) that accepts a two-dimensional array and returns a new version of the array with its columns and rows switched.
*/

function trans2dArray(arr) {
    let result = [];
    for (let col = 0; col < arr[0].length; col++) {
        let newRow = [];
        for (let row = 0; row < arr.length; row++) {
            newRow.push(arr[row][col])
        }
        result.push(newRow);
    }
    return result;
