What is the simplest way to print a counter after a loop has finished?

If I run the following code it will output 0.

var total = 0;
for(var i = i; i <= 100; i++) {
    total = total + i;
}
console.log(total);

This is because the line console.log(total) doesn't wait for the loop to finish; it just immediately executes.

How can I print the final value of total?

Change for loop to

for(var i = 0; i <= 100; i++) { //i=0 instead of i = i

i = i will cause i = undefined and that will cause i < 100 to fail

There is a mistake in your code:

change:

for(var i = i; i <= 100; i++)

To:

for(var i = 0; i <= 100; i++)

And it works:

var total = 0;
for(var i = 0; i <= 100; i++) {
    total = total + i;
}
console.log(total);
