js pop array element

let animals = ["dog","cat","tiger"];

animals.pop(); // ["dog","cat"]

animals.push("elephant"); // ["dog","cat","elephant"]

let cats = ['Bob'];

cats.unshift('Willy'); // ['Willy', 'Bob']

cats.unshift('Puff', 'George'); // ['Puff', 'George', 'Willy', 'Bob']

 let array = ["A", "B", "C"];

//Removes the last element of the array
 array.pop();

//===========================
 console.log(array);
//output =>
//["A", "B"]

//if you want to remove more varibles in the array,
//insted of using push you can simply define the length of the array 
 let array1 = [1, 2, 3, 4, 5, 6];
  
//Defines the length of the array to 2, removing the elements
//after the second element
 array1.length = 2;
  
//===========================
 console.log(array1);
//output =>
//["1", "2"]

var array = ['A', 'B', 'C'];
// removes and returns last element
lastElement = array.pop();

let cats = ['Bob', 'Willy', 'Mini'];

var fruits = ["Banana", "Orange", "Apple", "Mango"]
