Courses Plus Student 595 Pointsfor loop
Create a for loop that logs the numbers 4 to 156 to the console. To log a value to the console use the console.log( ) method.
var i;
for( i=0; i <+ 156; i += 4) {
console.log(i)
document.write(i);
}
I can't really understand the question, what does it want me to do ??

The Challenge wants you to console.log() some numbers. Specifically, it wants you to log the numbers 4 through 156, inclusive. You've almost done it in your for-loop above... just a few syntax and logic errors:
- "<+" is not valid syntax for anything. What you want is the less-than-or-equal-to operator, which looks like this: "<="
- "i += 4" is telling your for-loop to essentially count by 4. Since you're starting at i=0, that means the numbers you ultimately log will be: 0, 4, 8, 12, 16 etc. Obviously, this isn't what the Challenge wants you to do. The Challenge wants you to start at 4 and count by 1 until you reach 156. Let me know if you need further hints on this.
- Finally, there is no need for document.write(). The Challenge just wants you to console.log your numbers.

I think this is correct, no? I'm still not sure where, when, or why I would use this. I mean I think I know why, to repeat an aspect of code without writing it 156 times. Ok, I just answered my own question. Ain't coding fun and challenging?!?!!?!?!?! What I don't understand is why no semicolon needed after parenthesis (spelling). And why is it called a for loop?
