示例1:
const orSpec: S.Spec = S.spec.or("or test", { ball: (value: any) => value === "whale", fish: S.spec.number });
const nilableSpec: S.Spec = S.spec.nilable("nilable test", (value: any) => false);
const collectionSpec: S.Spec = S.spec.collection("collection test", S.spec.positive);
const collection2Spec: S.Spec = S.spec.collection("collection test", S.spec.string, {[S.symbol.count]: 3});
const tupleSpec: S.Spec = S.spec.tuple("tuple test", S.spec.bool, S.spec.date, S.spec.array);
const mapSpec: S.Spec = S.spec.map("map test", { email: S.spec.string, [S.symbol.optional]: { name: S.spec.string } });
const oneOfSpec: S.Spec = S.spec.oneOf("oneOf test", "a", "b", "c");
const predicateSpec: S.Spec = S.spec.predicate("predicate test", (value) => true);
// Predicates
const intPred: S.Predicate = S.spec.int;
const integerPred: S.Predicate = S.spec.integer;
const finitePred: S.Predicate = S.spec.finite;
const numberPred: S.Predicate = S.spec.number;
const oddPred: S.Predicate = S.spec.odd;
const evenPred: S.Predicate = S.spec.even;
示例2:
import * as S from "js.spec";
const spec: S.Spec = S.spec.predicate("test spec", S.spec.bool);
const c: symbol = spec.conform("water");
const waterProblems: S.Problem[] = spec.explain(["data"], ["spec"], "water");
const toString: string = spec.toString();
const name: string = spec.name;
const options: object = spec.options;
const isValid: boolean = S.valid(S.spec.boolean, true);

const problemStr: string = S.problemStr(problems[0]);
const explainStr: string = S.explainStr(S.spec.even, 3);
S.explainStr((value) => true, "a value");
// $ExpectType void
S.explain(S.spec.positive, true);
