How can I delete one element from an array by value

Question

I have an array of elements in Ruby

[2,4,6,3,8]

I need to remove elements with value 3 for example

How do I do that?<

Answer 1

I'm not sure if anyone has stated this, but Array.delete() and -= value will delete every instance of the value passed to it within the Array. In order to delete the first instance of the particular element you could do something like

arr = [1,3,2,44,5]
arr.delete_at(arr.index(44))

#=> [1,3,2,5]

There could be a simpler way. I'm not saying this is best practice, but it is something that should be recognized.
