Array

Overview

The framework re-exports lodash-es via the facade for array manipulation. All lodash array methods are available through a single import.

Import

import { lodash } from "@/framework/facade.js";

Common Methods

Method	Purpose
lodash.chunk(array, size)	Splits array into groups of the given size
lodash.compact(array)	Removes falsy values (false, null, 0, "", undefined, NaN)
lodash.uniq(array)	Creates a duplicate-free version of the array
lodash.uniqBy(array, iteratee)	Removes duplicates based on a criteria
lodash.difference(array, values)	Returns elements in array not present in values
lodash.intersection(arrays)	Returns elements present in all arrays
lodash.pull(array, ...values)	Removes all given values from the array (mutates)
lodash.remove(array, predicate)	Removes elements that match the predicate (mutates)
lodash.orderBy(array, keys, orders)	Stable sort by multiple columns
lodash.groupBy(array, iteratee)	Groups elements by a key
lodash.keyBy(array, iteratee)	Creates an object keyed by the iteratee result
lodash.maxBy(array, iteratee)	Returns the element with the maximum value
lodash.minBy(array, iteratee)	Returns the element with the minimum value
lodash.flatMap(array, iteratee)	Maps and flattens one level

Usage

import { lodash } from "@/framework/facade.js";

const users = [
  { name: "Alice", role: "admin" },
  { name: "Bob", role: "user" },
  { name: "Charlie", role: "admin" },
];

lodash.groupBy(users, "role");
// { admin: [{ name: "Alice" }, { name: "Charlie" }], user: [{ name: "Bob" }] }

lodash.orderBy(users, ["name"], ["asc"]);
// [{ name: "Alice" }, { name: "Bob" }, { name: "Charlie" }]

lodash.uniqBy(users, "role");
// [{ name: "Alice", role: "admin" }, { name: "Bob", role: "user" }]
