Definition

Creates an object composed of the enumerable property paths of object that are not omitted. Part of Lodash Object since 0.1.0 (stable — not deprecated).

Note: Returns a new object — the source is not mutated. Remaining nested values are still shared by reference (shallow copy of kept props).

Syntax

Call _.omit. Start with this line.

Lodash
_.omit(object, [paths])
CallWhat it does
_.omit(object, [paths])Primary signature.
_.omit(object)Work with an object’s keys, values, or paths.

Prefer import omit from "lodash/omit" when you want a smaller bundle.

Library declarations
Lodash
_.omit(object, [paths])

Parameters

This method has no parameters beyond those shown in the signature.

Return Value

Return ValueDescription
*New object without those paths

Lodash Examples

Example 1 — Official: Omit a and c

Pass an array of top-level keys to remove.

Lodash
var object = { a: 1, b: '2', c: 3 };

_.omit(object, ['a', 'c']);
// → { b: '2' }
Try It Yourself

How It Works

  1. Clone. Start from enumerable props of object.
  2. Drop a. Remove key a.
  3. Drop c. Remove key c.
  4. Keep b. Only b: '2' remains.

Example 2 — Variadic Paths

Same result with separate string arguments.

Lodash
_.omit({ a: 1, b: '2', c: 3 }, 'a', 'c');
// → { b: '2' }
Try It Yourself

How It Works

  1. Rest args. 'a' and 'c' are paths.
  2. Same as array. Equivalent to ['a','c'].
  3. Result. Still { b: '2' }.
  4. Pick a style. Use whichever reads clearer in your code.

Example 3 — Nested Path

Omit a nested field with a path string.

Lodash
_.omit({ a: 1, b: { c: 2, d: 3 } }, 'b.c');
// → { a: 1, b: { d: 3 } }
Try It Yourself

How It Works

  1. Path. 'b.c' targets nested key c.
  2. Unset. Removes c under b.
  3. Keep. a and b.d remain.
  4. Use. Handy for stripping one nested secret field.

Example 4 — Missing Path

Omitting a path that does not exist is a no-op.

Lodash
_.omit({ a: 1 }, 'z');
// → { a: 1 }
Try It Yourself

How It Works

  1. No key z. Nothing to remove.
  2. Copy. Still returns a new object with a.
  3. Safe. No error for unknown paths.
  4. Idempotent. Safe to list optional fields.

Example 5 — omit vs pick

Opposite helpers: drop listed paths vs keep them.

Lodash
var object = { a: 1, b: '2', c: 3 };

_.omit(object, ['a', 'c']);
// → { b: '2' }

_.pick(object, ['a', 'c']);
// → { a: 1, c: 3 }
Try It Yourself

How It Works

  1. omit. Removes a and c → keeps b.
  2. pick. Keeps only a and c.
  3. Choose. Short denylist → omit; short allowlist → pick.
  4. Source. Unchanged in both cases.
Compatibility

Browser & Runtime Support

Bottom line: Safe for production once Lodash is loaded. Prefer import omit from "lodash/omit" for smaller bundles. Use it to strip known paths without mutating the source.

Frequently Asked Questions

_.omit(object, …paths) returns a new object with all enumerable string keys from object except the listed paths. Official: _.omit({a:1,b:'2',c:3}, ['a','c']) → {b:'2'}.
No. It returns a new object. The source is left unchanged.
As an array (_.omit(obj, ['a','c'])) or as separate arguments (_.omit(obj, 'a', 'c')). Both forms work.
Yes. Pass a path string like 'b.c' or a path array. The parent object is copied with that nested key removed.
omit keeps everything except the listed paths. pick keeps only the listed paths.
Use import omit from "lodash/omit" or require("lodash/omit") for tree-shaking. Full build: import _ from "lodash" then _.omit.

Next: _.omitBy()

Omit properties whose values fail (or pass) a predicate.
