for (var i = 4; i <= 156; i++) { console.log([i]); } I dont know

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

Your for loop is not true. The square brackets aren't used for calling out the single variable.

Listen nipi u have messed the for loop's theory up The correct code is this

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

U dont put 'i' inside of square brackets when u are just logging the number out to the console or when u are printing stuff directly to the document using document.write

U ONLY put [i] when u are dealing with arrays Lets say u have an array called 'colors'..inside that array u have 5 array items. If you want to loop through these array items u can do it with a for loop like this.....

for(var i = 0; i < colors.length; i++){
   console.log(colors[i]);
}

Remember...u only use the counter with square brackets like this '[i]' only when looping through arrays Mark my answer as the best if i managed to help u
