[The distinction between "arguments" and "parameters"] #args #params #vs

arguments vs parameters.js

/*
  Arguments are used when a function is being called. 
  We pass arguments to functions. 
  Parameters are set up when the function is defined. 
  So it is said that parameters are used to define a function and arguments are used to invoke a function. 
  These words are typically interchangeable but knowing the distinction can be handy.

    return x+y+z
