To calculate the sum of an array of objects, the “for” loop and “reduce()” method of the array class can be utilized in JavaScript.
Array Sum = 149 Find the Sum of an Array by Using the reduce Method in JavaIn this example, we used the reduced() method directly with the stream of arrays and get the sum of the elements. Here’s how to do it:import java.util.Arrays; public class SimpleTesting { public static ...
function arraySum(arr) { var sum = 0; if (Object.prototype.toString.call(arr) === '[object Array]') { for (var i = 0; i < arr.length; i++) { if (typeof arr[i] === "number" && !isNaN(arr[i])) { sum += arr[i]; } else { va...
Using Array.reduce() method There is an inbuiltreducemethod in JavaScript which helps to calculate the sum of numbers in the array. letarr=[1,2,3,4,5];constsum=arr.reduce((result,number)=>result+number);console.log(sum)// 15
