Array API: Array.of()

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']);
