Array.of() creates an array with the given arguments as elements.
Array.of creates an array with the given arguments as elements
dont mix it up with `Array(10)', where the argument is the array length
const arr = Array(10);
assert.deepEqual(arr, [10]);puts all arguments into array elements
const arr = Array.of();
assert.deepEqual(arr, [1, 2]);takes any kind and number of arguments
const starter = [1, 2];
const end = [3, '4'];
const arr = Array.of(...starter, ...end);
assert.deepEqual(arr, [[1, 2], 3, '4']);
