Stuck in a for loop

Hmmm...can someone smarter than me please help me out? I feel like my error is a dumb one, but I can't seem to figure it out. I am trying to create a 'for' loop that logs the number 4 - 56 in a console.log method. In advance, thank you!

A for loop has 3 parts initialization, condition and final-expression. your var i = 4 is is the initialization. You condition is wrong. You needs something that going to go to true or false. so i < 100 is an example. Your final expression runs ever time the loop runs. So if you want to go from 4 to 100 you would do i++. Here is what that looks like

for(var i = 4; i < 100; i++) {
  console.log(i);
}

Here is the code that worked for me: for (var i = 4; i < 157; i = i + 1) { console.log(i); }
