omitBy() function

返回对象的部分副本,仅包含满足提供的谓词的键。

Signature:

declare function omitBy<T extends object, F extends AsyncEntryPredicate<T>>(
  f: F,
  obj: T,
): Promise<Partial<T>>;

Example

const obj = { a: 1, b: "2", c: true };
omitBy(([key, value]) => key === "a" || value === true, obj); // { b: "2" }

// asynchronous predicate
await omitBy(async ([key, value]) => key === "a" || value === true, obj); // { b: "2" }

// Using with the `pipe` function
pipe(
  obj,
  omitBy(([key, value]) => key === "a" || value === true),
);

await pipe(
  obj,
  omitBy(async ([key, value]) => key === "a" || value === true),
);
