Calculation method and processing rules
The type declaration is recursively generated according to the type of the sample value, and the field name is referenced using a JSON string.
scope of use
Inferred only according to the example; the empty array is deduced to unknown[], and the optional field or runtime check is not inferred.
Can the generated type replace the interface check?
Can't. It only infers the static type according to this JSON sample, and does not know all the cases of the interface, and does not generate runtime checks. An empty array will generate unknown[], and the optional fields that do not appear in the sample need to be supplemented by the developer.
Will the input content be saved on the server?
This tool handles input in the browser, and does not upload files or form content. Typing practice scores are only saved in the native browser.
Why may the result be different from other tools?
Inferred only according to the example; the empty array is deduced to unknown[], and the optional field or runtime check is not inferred. Please compare the input unit, rounding method, applicable rules and data version first.
