// The value of this in a function is sometimes called the "context" in which
// the function runs. The most important thing to understand is that a function
// object does not have a fixed context -- the value of this changes depending
// on how the function is called.

// If the function is called as a "raw" function (e.g., just do someFunc()),
// this will be window (or undefined if the function runs in strict mode).
