Warnings:

• In C language, the declaration of a function may also include a function prototype. This defines the calling interface to the function so that the compiler can give warning about any function calls that do not conform to the prototype.

• JavaScript does not support this function prototyping because it is not a strongly typed language and the scripts are not compiled before execution. Do not confuse function prototype calling interface specifications with the JavaScript Function.prototype object, which is part of the inheritance mechanism.
