I have tried to make a while loop where I add all the numbers of the array to one sum. I keep on getting an endless loop. I've also tried to do (array.length) (array.length --) (array.length>numbers) But nothing I tried worked... any suggestions? :)
function sumNumbersWhileLoop(array, sum) {
array = [1, 5, 4, 6, 7];
sum = 0;
for (let numbers of array) {
while (array.length>0) {
sum += numbers;
console.log(sum);
}
}
}
You don't need the while loop. The for...of loop is going to iterate over the array till its length.
function sumNumbersWhileLoop(array, sum) {
array = [1, 5, 4, 6, 7];
sum = 0;
for (let numbers of array) {
sum += numbers;
}
console.log(sum)
}
sumNumbersWhileLoop();If you want to use while, or reduce, then you can do the following:
function sumNumbersWhileLoop() {
const array = [1, 5, 4, 6, 7];
let len = array.length - 1;
let sum = 0;
while (len >=0) {
sum += array[len--];
}
console.log(sum);
// Or use reduce :
const reduceSum = array.reduce((acc, item) => acc + item, 0);
console.log(reduceSum);
}
sumNumbersWhileLoop();You can try this:
function sum(arr, sum) {
arr = [1, 5, 4, 6, 7];
sum = 0;
while (arr.length > 0) {
sum += arr.pop();
}
return sum;
}
console.log(sum());
