Question

function main() {
//tomando el número de vuelo y su estado
var levels = parseInt(readLine(),10);
var points = new Array();

var count = 0;
while(count<levels){
var elem = parseInt(readLine(),10);
points[count] = elem;
count++;
}

var sum = 0;
//calcula la suma de puntos

//la salida
console.log(sum);
}

Answer 1

Seems like you want to calculate the sum of all values stored in points array.
Here's the snippet that will solve your problem:

// calculating sum of elements in array points
var sum = 0;
for(var count = 0; count < levels; count++) {
sum = sum + points[count];
}

Since you know how many elements you need to read, a FOR loop is the best choice.
Although this code is correct, I suggest you to start writing cleaner code. Here's how this code could be rewritten:

function main() {
const LEVELS = parseInt(readLine(), 10)
let points = []
let sum = 0

// reading values of array points
for(let i = 0; i < LEVELS; i++)
points[i] = parseInt(readLine(), 10)

// calculating sum of elements in array points
for(let i = 0; i < LEVELS; i++)
sum += points[i]

/* You can also merge the above FOR loops
for(let i = 0; i < LEVELS; i++) {
points[i] = parseInt(readLine(), 10)
sum += points[i]
}
*/

console.log(sum)
}

Happy coding!
