Real Quick Question...

[Jeff Miller]

Hello,
Let's say I have an array like this:

@name_array = ["john", "t.", "smith"]

how can I get the first and LAST entries? IE:, I don't want the middle
one or any in between. I know I can get the first entry by
@name_array[0], but this will be part of a function in which some arrays
will have 2 entries, others 3 or even more, and I just want the last
entry. How can I do this?

Thanks!!

wait... sorry, my brain is tiered... array.first, array.last

Hello,
Let's say I have an array like this:

@name_array = ["john", "t.", "smith"]

how can I get the first and LAST entries?

[@name_array.first, @name_array.last]

or

@name_array.values_at(0,-1)

quite surprisingly: @name_array.first and @name_array.last

Hello,
Let's say I have an array like this:

@name_array = ["john", "t.", "smith"]

how can I get the first and LAST entries? IE:, I don't want the middle

[1,2,3].first => 1
[1,2,3].last => 3

Or have I missed something?

thanks guys, I knew it, my brain just didn't want to cooperate with me
for a minute...

While I'm writing a reply, I have another question: Is there something I
can do to make my script wait for a second or two? Like a pause or
something?

Thanks!

sleep n

Where "n" is some number of a Float.

Heh...this entire exchange should be put up on ruby-lang! It would be
the perfect advertisement:

"Imagine a programming language where the answers to simple questions
are not only simple, but you get 3 answers in under 15 minutes!"

first = array[0]
last = array[-1]
