Question

Write a odd and Even Array List in java script.

plz ///explain cleary and plz give a correct which run; postedbefore got code but it does not run

Answer 1

The Javascript code to seperate even, odd numbers from a list is:

//Creating a array with some numbers
var nums = [11,29,32,24,55,94,33,1,19,47,54,66,17];

//Creating two more arrays to store even and odd numbers seperately
var evens = [];
var odds = [];

//A function evenNumbers(nums) t seperate even,odd numbers in nums list
var evenNumbers = function(nums) {
  //Iterating through every number in nums list using for loop
  //nums.length returns length of nums array
    for (var i = 0; i < nums.length; i++) {

      //If the number at index i in nums array is divisible by 2 then it is even.
      //a%b gives the remainder when a is divided by b
        if ((nums[i] % 2) == 0) {
          //Adding this number to even array
            evens.push(nums[i]);
        }
        //Else it is odd number
        else {
          //Adding this number to odd array
            odds.push(nums[i]); 
        }
    }

};

//calling evenNumbers() function
evenNumbers(nums);

//Displaying even numbers, odd numbers arrays seperately
console.log("Even numbers in given list: ");
console.log(evens);
console.log("Odd numbers in given list: ");
console.log(odds);

I have declared and initialized a array called nums[] with some numbers. The I have created two more empty arrays even[ ] and odd[ ] to store the even and odd numbers of nums[] array seperately. I have called a function evenNumbers(nums) which checks if a number in the nums[] array is even or odd by dividing it by 2 and checking if remainder is 0. If remainder is 0 then it will add the number to even[ ] array using push() function else it will add number to odds[] array using push() function. We check this to all numbers in array nums by using a for loop that iterates till loop variable is less than length of nums[ ] array.

Then i have printed the output to the console using console() function. I have provided comments in the code explaining the process. I have tested the code and validated output. I am sharing output screenshot for your reference.

You can change numbers in the list nums[] and check for different cases.

Hope this answer helps you.

Thank you :)
