Question

Attempt:

function sum_even() {
var sum = 0;
for ( var i = 4; i < 387; i++) {
if (i % 2==0) {
sum +=i;
}
}
return sum;
}

Answer 1

Your i is sometimes lower, sometimes upper. Otherwise looks like it should work actually. 🤔

What exactly goes wrong?

Answer 2

Do you call it?

Answer 3

A function is a sub-code that only runs if you call it.

Write this under your function:

console.log(sum_even());

(First tidy up the syntax though. For also can't start with capital.)

Answer 4

It's not 387..its 401

Answer 5

When I run it am getting blank on my console.

Answer 6

What do you mean by call?

Answer 7

just after the function

Answer 8

Yeah.
