Adding to an Array

Rails
1

Hello,
I’ve been looking at the array stuff in the Noobkit, but I can’t seem
to find how to insert another entry in the array… Pretty much, I’m
going to be iterating through stuff and catching some things and adding
them to an array. I want to always add to the end of the array… In
stuff I’ve seen, you must define an index.

Any suggestions?

Thanks,

@a = Array.new
@a.push “item1”
@a << “item2”
@a.join(",") => “item1”, “item2”

that’s not correct. This is what it does:

a = Array.new
=> []
a.push “item1”
=> [“item1”]
a << “item2”
=> [“item1”, “item2”]
a.join(“,”)
=> “item1,item2”
