In JavaScript, there are several ways that control can be moved from one piece of code to another. Generally, code will be evaluated from left-to-right and top-to-bottom until it reaches any of the following situations:

• Invoking (invocation of a function by fn(), fn`` or new fn())
• Returning (returning from a function via either implicit or explicit return)
• Yielding (yielding from a generator via yield)
• Breaking (breaking from a loop or switch via break)
• Continuing (continuing an iteration via continue)
• Throwing (throwing an exception via throw)
