for loop

Each time i run this code ,i get a message that "your code took too long to run" , i am not sure what i'm doing wrong. Should there be any thing in the set of braces?

script.js 
for(var i = 1; 4<i<156; i+=1){


}
document.write(i);

your code should look like this :

for ( var i=4 ; i<157 ; i++ ) {
document.write(i);
}

and if you want to add every number in a separate line use this :

document.write(i + "<br>");

Hi Matthew, yes there should be something in the pair of curly braces and that is the console.log() statement. The conditions you used to construct your 'for' loop is what is making it take too long to run. Here's a more concise way:

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

Here you start at the value of 4 and iterate through as the number increases by 1 each time the loop runs until the number is equal to 156. Any number above 156, the loop stops running.
