conformsTo (Lodash Compatibility)

Checks if an object satisfies all given condition functions.

const result = conformsTo(target, source);

Reference

conformsTo(target, source)

Use conformsTo when you need to check if an object's properties satisfy all specified conditions. It applies each condition function to the corresponding property to check the results.

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

// Basic usage
const object = { a: 1, b: 2 };
const conditions = {
  a: n => n > 0,
  b: n => n > 1,
};

conformsTo(object, conditions); // true (all conditions satisfied)

// Various conditions
const user = { name: 'Alice', age: 25, active: true };
const userValidation = {
  name: s => typeof s === 'string' && s.length > 0,
  age: n => typeof n === 'number' && n >= 18,
  active: b => typeof b === 'boolean',
};

conformsTo(user, userValidation); // true

// When conditions are not satisfied
const invalidUser = { name: '', age: 15, active: 'yes' };
conformsTo(invalidUser, userValidation); // false

// Partial condition checking
const partialConditions = {
  age: n => n >= 21,
};
conformsTo(user, partialConditions); // true (only checks age)

// When property is missing
const incompleteObject = { a: 1 }; // no b property
const strictConditions = {
  a: n => n > 0,
  b: n => n > 0,
};
conformsTo(incompleteObject, strictConditions); // false (b property is missing)

Parameters

• target (Record<PropertyKey, any>): The object to inspect.
• source (Record<PropertyKey, (value: any) => boolean>): An object with condition functions for each property.

Returns

(boolean): Returns true if the object satisfies all conditions, otherwise false.
