For loop not running

I cannot figure out why there is a syntax error in here:

for ( i = 4; i <= 156; i += 1;) { console.log(i); } console.log(i);

script.js 
for ( i = 4; i <= 156; i += 1;) {
  console.log(i);
}
console.log(i);

You don't need a semi-colon after the counter. 

//Your coding is:
for ( i = 4; i <= 156; i += 1;) {
  console.log(i);
}

// You don't put a semi-color after i+=1. You coding should look like this:
for(i=4; i<=156; i+=1) {
   console.log(i);
}

// Also, always use var in front of i, if I is not already initialized. So, your coding should be:
for(var i = 4; i <= 156; i+=1){
   console.log(i);
}
