These 3 components may be represented in hexadecimal. 
A hexadecimal representation of the 3 components is called a triplet, or group of 3 numbers.

/*
  Functions containing no free/unbound variables are called pure functions.
  Functions containing one or more free variables are called closures.

  Adapted from the quick exercise in https://leanpub.com/javascript-allonge/read#closures

  If pure functions can contain closures, can a closure contain a pure function? 
  Attempt to compose a closure that contains a pure function.
  
  Many thanks to @raganwald!
