My console log looks like this: 12345678910111213141516......156. Why is that not a correct answer?

This is the code I came up with...

var numbers = '';

for(var i = 4; i < 157; i+=1){ numbers += i; }

console.log(numbers);

  1. Your console.log should be inside the for loop
  2. You want to print 'i' in the console, not 'numbers'
  3. No need to set an empty 'numbers' variable at the top
for ( var i = 4; i <= 156; i += 1 ) { console.log(i); }

and 4. In the parameters for the for loop, you already tell the loop to add 1 to 'i' every time you go through the loop (i += 1). No need to set that inside the for loop.

Ok, I swear this is what I had originally but I got an error about calling the console.log function 156 times.
