  Return -1L if str is not an index, or the index value as lower 32 bits of the result. Note that the result needs to be cast to an int in order to produce the actual index, which may be negative.
  Note that this method on its own does not actually produce an index that is useful for an actual Object or Array, because it may be larger than Integer.MAX_VALUE. Most callers should instead call toStringOrIndex, which calls this under the covers.

- bind
  
  public static Scriptable bind(Context cx, Scriptable scope, String id)
  
  Returns the object in the scope chain that has a given property.
  The order of evaluation of an assignment expression involves evaluating the lhs to a reference, evaluating the rhs, and then modifying the reference with the rhs value. This method is used to 'bind' the given name to an object containing that property so that the side effects of evaluating the rhs do not affect which property is modified. Typically used in conjunction with setName.

- toPrimitive

  The abstract operation ToPrimitive takes argument input (an ECMAScript language value) and optional argument preferredType (string or number) and returns either a normal completion containing an ECMAScript language value or a throw completion. It converts its input argument to a non-Object type. If an object is capable of converting to more than one primitive type, it may use the optional hint preferredType to favour that type.
  Parameters:

  public static boolean in(Object a, Object b, Context cx)
  
  The in operator.
  This is a new JS 1.3 language feature. The in operator mirrors the operation of the for .. in construct, and tests whether the rhs has the property given by the lhs. It is different from the for .. in construct in that:
  - it doesn't perform ToObject on the right hand side
  - it returns true for DontEnum properties.
  
  Parameters:
  
  a - the left hand operand
  
  b - the right hand operand
