You could specify the index and then iterate over the array and splice the inner arrays.

var array = [["a", "b", "c", "d", "e", "f"], ["a", "b", "c", "d", "e", "f"], ["a", "b", "c", "d", "e", "f"]],
    index = 1;

array.forEach(a => a.splice(index, 1));

console.log(array);

.as-console-wrapper { max-height: 100% !important; top: 0; }
