How can I delete an element from an array using its index?

Question

Trying to delete from this array:

array = ["Dog", "Cat", "John Cena"]

But those won't work:

array.delete(1)
array.delete([1])

Any help is appreciated.

Answer 1

It's delete_at you needed:

array = ["Dog", "Cat", "John Cena"]
#=> ["Dog", "Cat", "John Cena"]
array.delete_at(1)
#=> "Cat"
array
#=> ["Dog", "John Cena"]

Please check the doc more often, you'll probably find the thing you needed most of the times.

Answer 2

Alternatively:

array = ["Dog", "Cat", "John Cena"]
array[1, 1] = []
array # => ["Dog", "John Cena"]

Answer 3

As stated before you should be using Ruby Docs for help like this Ruby has amazing documentation and is a shame to waste the wealth of knowledge here.
