I don't get whats going on here, keep getting errors

Here is the code challenge below, and this is the error I am getting:

ode whileLoops.js
/home/treehouse/workspace/whileLoops.js:110
function print(text) s
^

SyntaxError: Unexpected identifier
at createScript (vm.js:80:10)
at Object.runInThisContext (vm.js:139:10)

at Function.Module._load (module.js:498:3)
at Function.Module.runMain (module.js:694:10)
at startup (bootstrap_node.js:204:16)

here is the code 

let i;
let text;

// from 0 to 4, 



print('1st Loop:');
text = '';

// Write 1st loop here:
i=0;
while (i<=4) {


text += i + '  ';

  i+= 1  ;
}

print(text); // Should print `0 1 2 3 4 `.

// 2. Write a while loop to build a string of numbers from 1 to 5, 
//    separated by spaces, and store the string in the variable `text`.
print('2nd Loop:');
text = '';

// Write 2nd loop here:

i=1;

while (i<=5) {


text += i + '  ';

  i+= 1  ; 
}


print(text); // Should print `1 2 3 4 5 `.

// 3. Write a while loop to build a string of numbers from 5 to 1, 
//    separated by spaces, and store the string in the variable `text`.
print('3rd Loop:');
text = '';



// Write 3rd loop here:


  i=5;

while (i<=0) {


text += i + '  ';

  i-= 1  ;
}

print(text); // Should print `5 4 3 2 1 `.

// 4. Write a while loop to build a string of numbers from 5 to 50--by 5's.
//    The numbers should be separated by spaces, and stored in the variable `text`.
print('4th Loop:');
text = '';

// Write 4th loop here:

  i=5;

while (i<=50) {


text += i + '  ';

  i+= 5;
}

print(text); // Should print `5 10 15 20 25 30 35 40 45 50 `.

// 5. BONUS CHALLENGE: Write a while loop that builds a string of random integers
// between 0 and 9. Stop building the string when the number 8 comes up.
// Be sure that 8 does print as the last character. The resulting string 
// will be a random length.
print('5th Loop:');
text = '';

// Write 5th loop here:
i= Math.floor(Math.random() * 10) ;

while (i !== 8 ){

  text += i + '   ';

 i = Math.floor(Math.random() * 10) ;

  text += i;
}



print(text); // Should print something like `4 7 2 9 8 `, or `9 0 8 ` or `8 `.


// Feel free to ignore this print function. It just formats the output a bit.
function print(text) s
  console.log(text);
  if (!text.endsWith(':')) {
    console.log('');
          }
        }

Hey so I managed to figure it out lol, I was missing an '{' at the bottom of the code for the function & there was an 's' that should not have been there..

here is the solution, going to keep it here in case it helps anyone :)

let i;
let text;

// from 0 to 4, 



print('1st Loop:');
text = '';

// Write 1st loop here:
i=0;
while (i<=4) {


text += i + '  ';

  i+= 1  ;
}

print(text); // Should print `0 1 2 3 4 `.

// 2. Write a while loop to build a string of numbers from 1 to 5, 
//    separated by spaces, and store the string in the variable `text`.
print('2nd Loop:');
text = '';

// Write 2nd loop here:

i=1;

while (i<=5) {


text += i + '  ';

  i+= 1  ; 
}


print(text); // Should print `1 2 3 4 5 `.

// 3. Write a while loop to build a string of numbers from 5 to 1, 
//    separated by spaces, and store the string in the variable `text`.
print('3rd Loop:');
text = '';



// Write 3rd loop here:


  i= 5;

while (i>=0) {


text += i + ' node  ';

  i -= 1  ;
}

print(text); // Should print `5 4 3 2 1 `.

// 4. Write a while loop to build a string of numbers from 5 to 50--by 5's.
//    The numbers should be separated by spaces, and stored in the variable `text`.
print('4th Loop:');
text = '';

// Write 4th loop here:

  i=5;

while (i<=50) {


text += i + '  ';

  i+= 5;
}

print(text); // Should print `5 10 15 20 25 30 35 40 45 50 `.

// 5. BONUS CHALLENGE: Write a while loop that builds a string of random integers
// between 0 and 9. Stop building the string when the number 8 comes up.
// Be sure that 8 does print as the last character. The resulting string 
// will be a random length.
print('5th Loop:');
text = '';

// Write 5th loop here:
i= Math.floor(Math.random() * 10) ;

while (i !== 8 ){

  text += i + '   ';

 i = Math.floor(Math.random() * 10) ;

  text += i;
}



print(text); // Should print something like `4 7 2 9 8 `, or `9 0 8 ` or `8 `.


// Feel free to ignore this print function. It just formats the output a bit.
function print(text) { 
  console.log(text);
  if (!text.endsWith(':')) {
    console.log('');
          }
        }

and here is the result

1st Loop:
0 1 2 3 4

2nd Loop:
1 2 3 4 5

3rd Loop:
5 4 3 2 1 0

4th Loop:
5 10 15 20 25 30 35 40 45 50

5th Loop:
1 33 33 33 8
