Sample source 3) JavaScript basic document structure (user-defined function _ parameters)

NS

If, through user-defined functions, we learned how to walk on our own rather than ride a stroller that the program gives and pulls along,
this time it's our turn to learn how to run.

Parameter... 매개변수 (parameter)... what a tough word...
Hmm.. I was kind of a lit major back in high school though... lol

For instance, if a user-defined function
is defining a useful function separately for various cases,
parameters
play the role of giving the programmer or user the opportunity to define or choose values depending on the situation.
Those chosen variables yield different result values, 
showing more diverse outputs and enabling more efficient communication between program and user.
