Usage

import { ss } from "@temelj/standard-schema";

const schema = ss.string();
const result = schema["~standard"].validate("hello");

SchemaFields names an object's field schemas. object validates those fields and strips other keys; strictObject rejects extra keys. looseObject preserves extra keys at runtime, but its output type exposes only the validated fields.

array() checks the container and returns unknown[]. Pass an element schema, such as array(string()), to validate its elements. fn() checks that a value is callable; it does not validate the function's parameters or result.

defaulted(schema, value) uses the supplied value, including function values. Use defaultedWith(schema, () => value) to create a default only when the input is undefined.
