Definition and Execution of Functions
The way that a function is defined is different from how it is executed
by a browser.
A function’s definition outlines its name, any parameters it may take,
and its statements.
NOTE: a definition doesn’t perform any of a function’s statements.
The code inside the function will execute when "something" invokes (calls)
the function:
- When an event occurs (when a user clicks a button)
- When it is invoked (called) from JavaScript code Automatically (self
invoked)
When JavaScript reaches a return statement, the function will stop
executing.
