Question:What's the meaning of arr?How to use it?
javascript is a Dynamic Scripting Language
var arr; // means that arr can be an integer,time(),array,etc.
arr = new Array() // means now arr is an array
arr[0] = new Array() // means that the first value of arr is an array
arr[1] = 12; // means the second value of arr is a integer
Damn English...
