Here we iterate over each element of the original array and then each number, checking if the sum of that index already existed, we just added the corresponding number to it othewise we set the corresponding num equal to it. Learn JavaScript in-depth with real-world projects through our Ja...
const array = [1, 2, 3, 4]; let sum = 0; for (let i = 0; i < array.length; i++) { sum += array[i]; } console.log(sum); We initialize a variable sum as 0 to store the result and use the for loop to visit each element and add them to the sum of the array....
the condition is set to “i < arr.length” which states that the while loop will run until the value of variable “i” reaches the length ofarr. Inside the loop, each array element would be summed up to the value ofsum.
Calculate the sum in array with condition, You can reduce() to an intermediate object, and then get its Object.values() : const data = [{ type: 'A', low: 1, mid: 2, high: 3, } Tags: input and sum the total calculating the sum of input javascript js get element value sum ...

Find the Sum of an Array by Using aforLoop in Java In this example, we used a loop to traverse each array element and get thir sum parallel. This method has a simple code that requires a single loop to get the sum. Here’s the example program: ...
importjava.util.Scanner;classExArrayElementSum{publicstaticvoidmain(String args[]){// create object of scanner.Scanner s=newScanner(System.in);intn,sum=0;// enter number of elements you want.System.out.print("Enter the elements you want : ");// read entered element and store it in "n...
log("Number of pair with sum " +sum +" is: " +countPair(arr, sum)); Using Hash MapIn this approach to count pairs with given sum, we will be using hash map. In this approach we make key-value pair of array elements with its frequecy and check the complement of element with ...
Write a JavaScript program to divide a given array of positive integers into two parts. First element belongs to the first part, second element belongs to the second part, and third element belongs to the first part and so on. Now compute the sum of two parts and store it in an array ...
