title: Why am I getting a Syntax error when using "class" in Javascript
body: <p>I am making a game in javascript, and I'm using making a class to hold all the sprites. However when I try to run it, safari gives me "SyntaxError: Unexpected use of reserved word 'class'". I can't find a reason it should be doing this. Below is my code:</p>
  
  <pre><code>var spritesContext;
  
  //Sprite class
  class sprite{
      constructor(imageName, imageX, imageY, imageHeight, imageWidth, context, canvas){
          this.imageName = imageName;
          this.imageX = imageX;
          this.imageY = imageY;
          this.imageHeight = imageHeight;
          this.imageWidth = imageWidth;
          this.canvas = canvas;
          this.context = context;
          spritesContext = context;
          console.log("Sprite constructed");
      }
  
      draw(){
          var character = new Image();
          character.src = "../Images/" + this.imageName + ".png";
          character.onload = function(){
              spritesContext.drawImage(character, this.imageX, this.imageY, this.imageWidth, this.imageHeight);
              console.log("Inner Draw is working.");
          }
          console.log("Draw is working.");
      }
  
      function getHeight(){
          return this.imageHeight;
      }
  
      function getWidth(){
           return this.imageWidth;
      }
  
      function getX(){
          return this.imageX;
      }
  
      function getY(){
         return this.imageY;
      }
  
      function moveUpX(e){
          this.imageX = (this.imageX + e);
      }
  
      function moveUpY(e){
          this.imageY = (this.imageY + e);
      }
  
      function moveBackX(e){
          this.imageX = (this.imageX - e);
      }
  
      function moveBackY(e){
         this.imageY = (this.imageY - e);
      }
  
      function changeImage(e){
          this.imageName = e;
      }
  
      function getImage(){
         return this.imageName;
      }
  
      function changeX(e){
           this.imageX = e;
      }
  
      function changeY(e){
          this.imageY = e;
      }
  
  }
