常见的想当然
In Babel presets, legacy configuration options like loose, spec, bugfixes, and useBuiltIns remain accepted as valid options, and isPluginRequired continues to be exported as a helper function.
这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。
契约
- Passing loose, spec, bugfixes, or useBuiltIns to @babel/preset-env in major version 8 throws descriptive removal errors rather than accepting legacy configuration options or polyfill strategies.
- Calling the exported isPluginRequired function throws an explicit removal error pointing to @babel/helper-compilation-targets.
- Preset initialization with valid target configuration succeeds without specifying bugfixes because bugfix plugins are enabled unconditionally in v8.
- Exported utility transformIncludesAndExcludes correctly categorizes plugins and builtIns into separate sets.
