I have a parse error. What is it?

Please review. What am I missing?

script.js 
for (var i = 0, i <= 24, i += 2) {
  console.log(i);
};

The bane of all programmers' existences: the dreaded semi-colon.

Should be:

for (var i = 2; i <= 24; i += 2) { console.log(i); };

You have:

for (var i = 2, i <= 24, i += 2) { console.log(i); };

Hi,

Tiny issue with your for loop there.

As you got :

for (var i = 0, i <= 24, i += 2) {
  console.log(i);
};

And what it is supposed to be:

for (var i = 0; i <= 24; i += 2) { // So no , but ; sings
  console.log(i);
};
