Util

Definition

Creates a function that checks whether all predicates return truthy for the arguments it receives. Supports matches / matchesProperty shorthands. Part of Lodash Util since 4.0.0 (stable — not deprecated).

Pass the arguments shown below. Prefer modular imports when you only need this helper.

Syntax

Call _.overEvery. Start with this line.

Lodash
_.overEvery([predicates=[_.identity]])
CallWhat it does
_.overEvery([predicates=[_.identity]])Primary signature.
_.overEvery(...)Call the util helper.

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

Library declarations
Lodash
_.overEvery([predicates=[_.identity]])

Parameters

ParameterDescription
predicatesOptional. Functions / shorthands (array and/or rest args)

Return Value

Return ValueDescription
*A function that returns true or false

Lodash Examples

Example 1 — Official: Boolean + isFinite

Both predicates must pass for the same value.

Lodash
var func = _.overEvery([Boolean, isFinite]);

func('1');
// → true

func(null);
// → false

func(NaN);
// → false
Try It Yourself

How It Works

  1. Build. Combine Boolean and isFinite.
  2. '1'. Truthy and finite → true.
  3. null. Boolean(null) fails → false.
  4. NaN. Truthy as Boolean, but not finite → false.

Example 2 — Matches Object Shorthand

Plain objects become _.matches predicates — all must match.

Lodash
var func = _.overEvery([{ a: 1 }, { b: 2 }]);

func({ a: 1, b: 2 });
// → true

func({ a: 1 });
// → false
Try It Yourself

How It Works

  1. Shorthand. Each object is a matches-style check.
  2. AND. Need a: 1 and b: 2.
  3. Full object. Both keys present → true.
  4. Partial. Missing b → false.

Example 3 — overEvery vs overSome

AND vs OR on the same predicates.

Lodash
var every = _.overEvery([Boolean, isFinite]);
var some = _.overSome([Boolean, isFinite]);

every(0);
// → false   (Boolean(0) fails)

some(0);
// → true    (isFinite(0) passes)
Try It Yourself

How It Works

  1. Zero. Falsy for Boolean, finite for isFinite.
  2. overEvery. Needs both → false.
  3. overSome. Needs one → true.
  4. Pick. Strict gate → every; loose gate → some.

Example 4 — Reuse with _.filter

Build a combinator once, then filter a list.

Lodash
var ok = _.overEvery([Boolean, isFinite]);

_.filter([1, 0, '2', null, NaN], ok);
// → [1, '2']
Try It Yourself

How It Works

  1. Combinator. ok is the overEvery function.
  2. Filter. Each item is tested with both predicates.
  3. Keep. 1 and '2' pass both checks.
  4. Drop. 0, null, NaN fail at least one.

Browser & Runtime Support

_.overEvery is a Lodash Util helper since 4.0.0. It runs anywhere Lodash runs — modern browsers (CDN or bundle) and Node.js / Bun / Deno with npm install lodash.

✓ Stable · Lodash 4.0.0+

_.overEvery()

Available in [email protected] full builds and the lodash/overEvery modular import. Works in evergreen browsers and current Node LTS when Lodash is installed.

Bottom line: Safe for production once Lodash is loaded. Prefer import overEvery from "lodash/overEvery" for smaller bundles.

Frequently Asked Questions

_.overEvery(predicates) returns a new function. When you call it, Lodash runs every predicate with the same arguments and returns true only if all results are truthy — otherwise false.
_.over returns an array of every result. _.overEvery returns one boolean: true when all predicates pass.
overEvery is logical AND (all must pass). overSome is logical OR (any may pass).
Yes. A plain object becomes a _.matches predicate; an array [path, value] becomes _.matchesProperty.
With [Boolean, isFinite]: func('1') → true, func(null) → false, func(NaN) → false.
No. It is a stable Lodash Util method since 4.0.0.

Next: _.overSome()

Combine predicates with OR — true if any check passes.
