Different ways to Sum Array Values in JavaScript (#shorts )

Hi Friends,

Different ways to Sum Array Values in JavaScript

There are several ways to sum array values in JavaScript, including:

Using the reduce() method:

let arr = [1, 2, 3, 4, 5];
let sum = arr.reduce((a, b) => a + b, 0);

console.log(sum); // Output: 15

Using the forEach() method:

let arr = [1, 2, 3, 4, 5];
let sum = 0;

arr.forEach((num) => {
sum += num;
});

console.log(sum); // Output: 15

Using the eval() function:

let arr = [1, 2, 3, 4, 5];
let sum = eval(arr.join("+"));

console.log(sum); // Output: 15

IMPORTANT NOTE: first two methods are recommended as they are more efficient and less prone to errors. The eval() function should be used with full caution as it can execute inconsistent code and may arise security risks if used improperly.
