Correct syntax needed for bind() on 'this' object using class

could be a nice idea - I'll have a think! I've been meaning to try some contests - for example I reckon now tweets are 280 chars you could do some really interesting things in hardware JS :)

@Robin as @allObjects says, each command you write on the left-hand side after you upload is changing the state of the interpreter. If you thought that each command you typed was executed on a fresh instance of your code it could actually be a really big cause of the problems you're having.

Please check out some of the comments below - they might help.

>var tb = new TestBind();
=TestBind: { "vX": 25 }
                        <---- was there a command missing here?
=25
>tb.setX = 42;          <---- after this, tb.setX is now set to 42. It's no longer
                              a function
=42                     
>print tb.getX();       <---- again, this is NOT how you use print or call a 
                              function in JS. if you want the console to say 
                              '=value' just type 'tb.getX()' 
                              - you don't need 'print'
=25
>var bg = g.bind(tb);   <---- as allObjects says - there must be some code here 
                              you're not posting up as you didn't define 'g' 
                              previously, but lets assume that code was 
                              'g = tb.getX()'. 'g' will be 25, so is a number 
                              and won't have a 'bind' method

var bg = g.bind(tb);

>print bg               <---- not how you call print, as mentioned above. However 
                              the code above errored so you wouldn't expect it to 
                              have written anything to 'bg'
=undefined
>tb.setX(42);           <---- If you did this right at the start, it would have 
                              worked. Since you called it after 'tb.setX = 42', 
                              'tb.setX' is now 42 so it is not a function you 
                              can call
