常见的想当然

Instantiating or catching AbortError yields an error object whose name property is 'AbortError' and code is 20 (DOMException.ABORT_ERR).

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

• AbortError instances have name set to 'Error' and code set to 0 rather than 'AbortError' and 20 because its constructor extends DOMException and invokes super(message) without the name argument
• AbortError constructor is exported identically from the package root and es-toolkit/error subpath
• delay rejects on aborted signal with an AbortError whose name is 'Error' and code is 0, discarding any custom signal reason
• catching AbortError requires instanceof or constructor.name checks rather than error.name equality
• isError returns true for AbortError while compat isError returns false due to the [object DOMException] tag
