function(thisOtherNumber){
  return numberToAdd + theOtherNumber;  
}

That function remembers variables numberToAdd that were around when the function was declared.

IIFE

• Avoid variable hoisting from within blocks
• Protect against polluting the global environment
• Simultaneously allow public access to methods....
