JavaScript: Compute the sum of three elements of a given array of integers of length 3

JavaScript Basic: Exercise-69 with Solution

Write a JavaScript program to compute the sum of three elements of a given array of integers of length 3.

Visual Presentation:

Sample Solution:

JavaScript Code:

// Define a function named sum_three that takes an array of three numbers as a parameter
function sum_three(nums) {
    // Return the sum of the three numbers using array indexing
    return nums[0] + nums[1] + nums[2];
}

// Call the function with different arrays and log the results to the console
console.log(sum_three([10, 32, 20]));
console.log(sum_three([5, 7, 9]));
console.log(sum_three([0, 8, -11]));

Output:

62
21
-3

Live Demo:

See the Pen JavaScript - compute the sum of three elements of a given array of integers of length 3 - basic-ex-69 by w3resource (@w3resource) on CodePen.

Flowchart:

ES6 Version:

// Define a function named sum_three with a parameter nums using arrow function syntax
const sum_three = nums => {
    // Use destructuring assignment to get individual elements of the array
    const [num1, num2, num3] = nums;
    // Return the sum of the three numbers
    return num1 + num2 + num3;
};

// Call the function with sample arguments and log the results to the console
console.log(sum_three([10, 32, 20]));
console.log(sum_three([5, 7, 9]));
console.log(sum_three([0, 8, -11]));
