arguments to array;

Array.prototype.slice.call (arguments);

Calculates the factorial of an integer

function factorialize (num) {  if(num==0)return 1;   return num*factorialize (num-1);}

Remove the number specified in the array

function Destroyer (arr) {  var args = array.from (arguments). Slice (1);   return arr.filter (function(val) {    return ! ) Args.includes (val);  });} Deestroyer ([1,2,3,1,2,4,7,8,6],1,2,3);

Remove the object containing the second argument from the first argument

functionvar keys=Object.keys (source);   return collection.filter (function(val) {        return keys.every (function  (key) {          return val.hasownproperty (key) &&val[key]==Source[key];        });   null }, {first: ' Tybalt ', Last: ' Capulet '}], {last: "Capulet"});

Take a different part of two arrays

function diff (Arr1, arr2) {  return arr1.filter (function(e) {return !arr2.includes (e) ;}). Concat (Arr2.filter (function(e) {return ! ) Arr1.includes (e);})); diff ([1, 2, 3, 5], [1, 2, 3, 4, 5]);
