In this lesson we are going to learn the properties of arrays, foreach usage, the jagged array I mentioned in the last lesson, I'll show you a few examples of how the jagged array definition has been better understood than the regular two-dimensional array (rectangular array), and we'll also learn the common methods of

Ways to change the original array:POPs (); Deletes the first element of the tail and returns the element; var a = [1,2,3]; var B = A.pop (); Console.log (a);//[1,2] Console.log (b);//3Similar methods: push (); tail pushing; returning array length; Shift (); top eject; return the element; Unshift (), top sub-entry, return array length, reverse (), reverse array, r

Pseudo-Arrays (class arrays): You cannot call an array method directly or expect any special behavior for the length property, but you can still traverse them with a true array traversal method. Typically, the argument parameters of a function, as well as calls to Getelementsbytagname,document.childnodes, are all returned nodelist objects are pseudo-arrays. You can use Array.prototype.slice.call (Fakearray)

Method One: Slice () method;var a=[1,5, ' ff ', ' g ', ' h ', ' SD ', ' G ']; Alert (Deletelast (a)); function Deletelast (arr) { returnarr.slice (0,arr.length-1); }Method Two: Concat () or slice () plus pop (); function Deletelast (arr) { // var newarr=arr.slice (0); var newarr=Arr.concat (); Newarr.pop (); return newarr; }5. Delete the last element of the array arr, withou
