Check if an array/hash contains a particular element

Hi,

Is there any convenient method to check if an array contains a
particular element? eg.

abc = {‘ele1’,‘ele2’}

if abc contains ‘ele1’
========
blablablab…
end

Thanks.

That’s a hash, not an array. I think you mean:

[“ele1”, “ele2”]

if abc contains ‘ele1’

if abc.include?(‘ele1’)
