///// Scopes /////

- As little variables in global scope as possible
- iffes (immediately invoked function) are useful for creating closure and private variables
- Do not mutate inputs.  But if you need to, be absolutely clear about it in your documentation

///// Closures /////

- Functions create new closure scopes
- A closure is a function object that retains ongoing access to the variables of the context it was created in (even after the outer function calls it was created within have returned)

/////// Example of using Regexp with match in order to find the number of vowels in a string ///////

var vowelCount = function(str) {
  var vowels = str.match(/[aeiou]/gi);
  // if str was 'hi there', vowels is equal to ['i', 'e', 'e']
  return (vowels === null) ? 0 : vowels.length;
};

/////// Example of how to use call to bind 'this' to the correct execution context ///////
