N
const array = [1, 2, 3];array.forEach(function(elem, index, array) { array[index] = elem * 2;});console.log(array); // [2,4,6]N
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.N
const array = [1,2,3,4,5];const evenNumbers = array.filter(function(elem) { // expressions that return 'true' are retained return elem % 2 == 0;});N
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]
