prototype Reference to the object's prototype. (IE4+ (JScript 2.0+), N3+ (JavaScript 1.1+), ECMA Edition 1)
Methods
apply(thisArg [, argArray]) Invokes the function with the object referenced by thisArg as its context (so references to this in the function reference thisArg).

call(thisArg [, arg1 [, arg2 [, ...]]]) Invokes the function with the object referenced by thisArg as its context (so references to this in the function reference thisArg). The optional parameters argN are passed to the function as it is invoked. (IE5.5+ (JScript 5.5+), N4.06+ (JavaScript 1.3+), MOZ, ECMA Edition 3)
toString() Returns the string version of the function source. The body of built-in and browser objects will typically be represented by the value "[native code]". (IE4+ (JScript 2.0+), N3+ (JavaScript 1.1+), MOZ, ECMA Edition 1)
valueOf() Returns the string version of the function source. The body of built-in and browser objects will typically be represented by the value "[native code]". (IE4+ (JScript 2.0+), N3+ (JavaScript 1.1+), MOZ, ECMA Edition 1)
