1.return out of the value, the execution of this function is finished, the statement after return will not be executed

2.arguments is the set of arguments inside the function that pass in

3. When you write a function, the number of functions can not be determined, the use of arguments more appropriate. (You can use Arguments.length)

4.setInterval (function, Time-ms)//repeat//set-timer

That is, SetInterval is, give a function, and then call it every few long, and execute it once.

Clearinterval (timer name)//clear-timer//In the event of more references
