Hash#transform_keys takes a hash
You can map keys by giving a map of new keys:
data = {
isAdmin: true,
firstName: "Luke",
lastName: "Walker"
}
data.transform_keys({
isAdmin: :admin?,
firstName: :first_name,
lastName: :last_name
})
=> {
:admin? => true,
:first_name => "Luke",
:last_ame => "Walker"
}
