toPairsIn (Lodash Compatibility)

Use Object.entries or for...in loop instead

This toPairsIn function operates slowly due to complex logic for handling inherited properties, Map and Set processing, etc.

Use faster and more modern Object.entries() or a for...in loop if you need inherited properties.

Converts an object to an array of key-value pairs, including inherited properties.

const pairs = toPairsIn(object);

Reference

toPairsIn(object)

Use toPairsIn when you want to convert all enumerable properties of an object (including inherited properties) to an array of [key, value] pairs. Unlike toPairs, properties in the prototype chain are also included.

import { toPairsIn } from 'es-toolkit/compat';

// Basic object conversion
const object = { a: 1, b: 2 };
toPairsIn(object);
// => [['a', 1], ['b', 2]]

// Include inherited properties
function Parent() {
  this.inherited = 'value';
}
Parent.prototype.proto = 'property';

const child = new Parent();
child.own = 'own';
toPairsIn(child);
// => [['inherited', 'value'], ['own', 'own'], ['proto', 'property']]

Can also handle Map and Set.

import { toPairsIn } from 'es-toolkit/compat';

// Map object conversion
const map = new Map([
  ['key1', 'value1'],
  ['key2', 'value2'],
]);
toPairsIn(map);
// => [['key1', 'value1'], ['key2', 'value2']]

// Set object conversion
const set = new Set([1, 2, 3]);
toPairsIn(set);
// => [[1, 1], [2, 2], [3, 3]]

Parameters

• object (object): The object, Map, or Set to convert.

Returns

(Array<[string, any]>): Returns an array of key-value pairs (including inherited properties).
