Add element at end of array

Hi there,

i'm pretty new to Ruby. I searched 'Programming Ruby' and the online documentation but couldn't find a solution. So please forgive me my simple question ;).

I just want to add a new value / object to an existing array. Right now i'm using

a[a.length] = 'foo'

but i'm almost sure Ruby has a better way to do that!?

Thx for any help
D.

this is short example :

a = [1,2,3,4]
=> [1, 2, 3, 4]

a.push(5)
=> [1, 2, 3, 4, 5]

Hi Daniel,

Yes, there is an easier way to do that:

a = [1,2,3]
a.push(4)

Best regards,
