For loop to get the total of all iterations in Javascript, using node.js

Question

I was trying to get the total of iterations in a for loop on Javascript using node.js. Here is my code

var sum = 0;
for (itr=1; itr<=5; itr++) {
    var lt = 8;
    var sum = sum+lt;
    console.log(sum);
}

So what I get here is a list of values as the output. How do I get the last value (the total of all iterations) 40 as a single output. Can someone please guide me through this?

Just move console.log(sum) outside your loop. Like this

var sum = 0;
for (itr=1; itr<=5; itr++) {
    var lt = 8;
    var sum = sum+lt;
}
console.log(sum);

BTW, two possible improvements:

remove the var in var sum = sum+lt;
make your iteration variable var, like this: for (var itr=1; itr<=5; itr++) {
