reverse array elements code example

Example 1: javascript reverse array

var arr = [34, 234, 567, 4];
print(arr);
var new_arr = arr.reverse();
print(new_arr);

Example 2: reverse string array java

//java program to reverse array using for loop
public class ReverseArrayDemo 
{
   public static void main(String[] args) 
   {
      int[] arrNumbers = new int[]{2, 4, 6, 8, 10};  
      System.out.println("Given array: ");  
      for(int a = 0; a < arrNumbers.length; a++)
      {
         System.out.print(arrNumbers[a] + " ");
      }
      System.out.println("Reverse array: ");
      // looping array in reverse order
      for(int a = arrNumbers.length - 1; a >= 0; a--) 
      {  
         System.out.print(arrNumbers[a] + " ");  
      }
   }
}

Example 3: reverse string array java

import java.util.Arrays;
public class ReverseStringArrayInJava
{
   public static void main(String[] args)
   {
      String[] strHierarchy = new String[]{"Junior Developer","Senior Developer","Team Lead","Project Manager","Senior Manager","CEO"};
      System.out.println("Given string array: " + Arrays.toString(strHierarchy));
      for(int a = 0; a < strHierarchy.length / 2; a++)
      {
         String strTemp = strHierarchy[a];
         strHierarchy[a] = strHierarchy[strHierarchy.length - a - 1];
         strHierarchy[strHierarchy.length - a - 1] = strTemp;
      }
      System.out.println("Reversed string array: ");
      for(int a = 0; a < strHierarchy.length; a++)
      {
         System.out.println(strHierarchy[a]);
      }
   }
}

Example 4: reverse array javascript

// reverse array with recursion function
function reverseArray (arr){
if (arr.length === 0){
return []
}
  return [arr.pop()].concat(reverseArray(arr))
}
console.log(reverseArray([1, 2, 3, 4, 5]))

Example 5: reverse array in javascript

const reverseArray = arr => arr.reduce((acc, val) =>  [val, ...acc], [])

Example 6: array reverse in javascript

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

fruits.reverse();
