3. Native Functions


          There are several predefined functions built into JavaScript and are used to answer certain requirements. There are native functions that are used to get and display information.  There are also functions that are used to convert one data type to another. Examples are the output functions discussed in the previous learning guides which are alert(), prompt() and confirm().  Other native or built-in functions will be discussed in the succeeding learning guides or as we progress with JavaCcript coding journey.
