function deepMerge

import { deepMerge } from "https://dotland.deno.dev/x/ultra@v2.3.0/lib/build/deps.ts";

deepMerge<T extends Record<PropertyKey, unknown>>(

record: Partial<Readonly<T>>,

other: Partial<Readonly<T>>,

options?: Readonly<DeepMergeOptions>,

): T

Merges the two given Records, recursively merging any nested Records with the second collection overriding the first in case of conflict

deepMerge<T extends Record<PropertyKey, unknown>, U extends Record<PropertyKey, unknown>, Options extends DeepMergeOptions>(

record: Readonly<T>,

other: Readonly<U>,

options?: Readonly<Options>,

): DeepMerge<T, U, Options>

Merges the two given Records, recursively merging any nested Records with the second collection overriding the first in case of conflict

For arrays, maps and sets, a merging strategy can be specified to either replace values, or merge them instead. Use includeNonEnumerable option to include non-enumerable properties too.
