import { isTupleOf } from "https://deno.land/x/unknownutil@v3.0.0/is.ts";
Return a type predicate function that returns true if the type of x is TupleOf<T>.
import is from "./is.ts";
const predTup = [is.Number, is.String, is.Boolean] as const;
const a: unknown = [0, "a", true];
if (is.TupleOf(predTup)(a)) {
// a is narrowed to [number, string, boolean]
const _: [number, string, boolean] = a;
}
Type Parameters
T extends readonly Predicate<unknown>[]
Parameters
predTup: T
