Häufige Annahme
Equivalent inline plugin option objects are reused across transformSync calls, and createConfigItem remains a synchronous convenience API in Babel 8.
So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.
Contract
- Fresh inline plugin option objects make transformSync execute the plugin factory once per call
- A ConfigItem created once with createConfigItemSync reuses its plugin descriptor so five transformSync calls execute the factory exactly once
- createConfigItem without a callback throws in Babel 8 and names createConfigItemSync as the synchronous replacement
- createConfigItemSync returns a frozen ConfigItem whose value and options retain the supplied plugin and option object
