function createRange(start, end) {
var numbers = [];
for (var i = start; i < end + 1; i += 1)
numbers.push(i);
return numbers;
function calculateSum() {
numbers.reduce(function (a, b) {
return a + b;
}, 0);
}
};
console.log(createRange(5, 15));
console.log(calculateSum());Could someone explain why I'm not getting the sum of numbers? The sum keeps showing as 0.
Your sum function should not be enclosed within the range function block. It is important that your sum function accepts an array parameter, and here is the updated code:
function range(start, end) {
var arr = [];
for (var i = start; i < end + 1; i += 1)
arr.push(i);
return arr;
}
function sum(arr) {
arr.reduce(function (a, b) {
return a + b;
}, 0);
}
var arr = range(5, 15);
console.log(arr);
console.log(sum(arr));
Check out this code snippet:
const generateRange = (start, end) => {
const result = [];
for (let i = start; i <= end; i++) {
result.push(i);
}
return result;
}
const calculateSum = (arr) => {
return arr.reduce((a, b) => a + b, 0);
}
const numbers = generateRange(5, 15);
console.log(numbers);
console.log(calculateSum(numbers));
The sum function needs to be defined within the correct scope for it to work properly.
Here is a solution:
function range(start, end) {
var arr = [];
for (var i = start; i < end + 1; i += 1)
arr.push(i);
return arr;
};
function sum(arr) {
return arr.reduce(function (a, b) {
return a + b;
}, 0);
}
console.log(range(5, 15));
console.log(sum(range(5, 15))); let numbers = [];
function generateRange(start, end) {
for (let i = start; i < end + 1; i += 1)
numbers.push(i);
return numbers;
}
function calculateSum() {
return numbers.reduce(function (a, b) {
return a + b;
}, 0);
}
console.log(generateRange(8, 20));
console.log(calculateSum());
