title: omit tags: object,array,intermediate

Omits the key-value pairs corresponding to the given keys from an object.

Use Object.keys(obj), Array.prototype.filter() and Array.prototype.includes() to remove the provided keys. Use Array.prototype.reduce() to convert the filtered keys back to an object with the corresponding key-value pairs.

const omit = (obj: AnyObject, arr: string[]) =>
  Object.keys(obj)
    .filter((k) => !arr.includes(k))
    .reduce((acc, key) => ((acc[key] = obj[key]), acc), {} as AnyObject);

omit({ a: 1, b: "2", c: 3 }, ["b"]); // { 'a': 1, 'c': 3 }
