The Array.of() method creates a new Array instance from a variable number of arguments, regardless of number or type of the arguments.
The difference between Array.of() and the Array constructor is in the handling of integer arguments: Array.of(7) creates an array with a single element, 7, whereas Array(7) creates an empty array with a length property of 7 (Note: this implies an array of 7 empty slots, not slots with actual undefined values).
Array.of(7); // [7] Array(7); // array of 7 empty slots Array.of(1, 2, 3); // [1, 2, 3] Array(1, 2, 3); // [1, 2, 3]
