.parse(*args, implied:, component_id: nil) ⇒ Object

‘.parse(*args, implied:)`:

(Symbol)         -> target `:name` on implied controller
(String)         -> target name as-is on implied (already js-cased)
(String, Symbol) -> explicit (controller_path, target_name)

.to_data_hash(targets) ⇒ Object

Same-key concat with space. Example:

Target(row)                       -> "foo-target" => "row"
Target(row) + Target(cell)        -> "foo-target" => "row cell"
Target(row) + Target(x, on: bar)  -> {"foo-target"=>"row", "bar-target"=>"x"}
