Array functions

Hi, 

Could you please tell me how to work with arrays in TestComplete using JScript, like I'm 5 years old?



I figured that I can initialize a new array like this:

aWords = new Array("apple", "bee", "cover", "blahblahblah")

and that I can get an array's length like this

iLength = aWords["length"]

and iterate like this

for (i = 0; i < aWords["length"]; i++)

{ DoSomething(aWords) }



But now I can't figure out how to

1) find an item in an array - first occurence/all occurences

2) compare 2 arrays "by value"

3) copy an array "by value"

4) check that an item belongs to an array

5) remove an item from an array

6) add an item to an array

7) add all items from one array to another



I mean, are there some Array functions that allow to do this stuff, or should I write them by myself?
