Getting UCE0001 error when trying to get score to display in pong game (JavaScript) [Solved]

I'm trying to learn how to script in unity and the first thing I'm trying to make is a pong game. I'm using a tutorial to learn how to do this, but it's in C#. I only know JavaScript(UnityScript), although I know enough to change things in C# so that they would work for my javascript scripts. I got a few things working, like moving the padle/bat and counting the score, but now I'm stuck on how to get the score displayed.

Here's the code:

 import UnityEngine.UI;
 
 var Bat1_score: int = 0;
 var Bat2_score: int = 0;
 
 var ScoreBoard: Text;
 var ball: GameObject;
 
 function Update () {
     if(ball.transform.position.x <= -16.4f) {
         Bat1_score ++;
         PrintScore();
     } else if (ball.transform.position.x >= 16.4f) {
         Bat2_score ++;
         PrintScore();
     }
 }
 
 function PrintScore() {
     print("Bat1: " + Bat1_score + ", " + "Bat2: " + Bat2_score);
     ScoreBoard.text = Bat1_score.ToString() + " - " Bat2_score.ToString();
 }

Now everything works, except line 21 or:

 ScoreBoard.text = Bat1_score.ToString() + " - " Bat2_score.ToString();

and the error I get is:

 Assets/Scripts/CountScore.js(21,54): UCE0001: ';' expected. Insert a semicolon at the end.

I've no idea what I'm doing wrong, so I can only guess that it's a syntax difference between C# and JavaScript that I'm not aware of. Thanks in advance.

Edit: I got my answer. It seems I forgot a + in a certain place.

Before:

 ScoreBoard.text = Bat1_score.ToString() + " - " Bat2_score.ToString();

After:

 ScoreBoard.text = Bat1_score.ToString() + " - " + Bat2_score.ToString();
