; expected. Insert a semicolon... C# & JavaScript 2D Controller

I'm trying to write a 2D Character controller scipt following the Unity Live 2D Character conrtoller tutorial. He's using C# and I'm using JavaScript. I'm trying to translate his script into JavaScript but clearly some mistakes still remain. Can you help me?

 #pragma strict
 
 var maxSpeed : float = 10;
 var facingRight = true;
 
 
 function Start () {
 
 }
 
 function FixedUpdate () {
 
         var flip = function(){
             facingRight - !facingRight; //flip the char
             var theScale : Vector3 = Transform.localScale; //get local scale
             theScale.x *= -1; //flip local scale
             Transform.localScale = theScale; //make the flip the new localScale
             } 
         
         
         var move: float = Input.GetAxis ("Horizontal"); //get the direction we are moving in
         rigidbody2D.velocity = new Vector2(move * maxSpeed, rigidbody2D.velocity.y); //make move speed float to the max speed
     
         if(move > 0 && !facingRight){
             flip();
             //if you are moving right and you are not facing right flip it. 
         }else if(move < 0 && facingRight){
             flip();
             //if you are moving left and you are not facing left flip it. 
             }
 
     
     
 
 
 }
