Array Helper

Lightweight standalone array utility functions — the parts of LoDash and Underscore you actually need, without the weight.

Install

npm install @deebeetech/array-helper

Functions

• orderBy
• uniqBy

orderBy

Sort an array by multiple keys and directions, returning a new array without mutating the original. Compares numbers numerically and everything else via localeCompare.

import { orderBy } from "@deebeetech/array-helper";

const users = [
   { name: "John", age: 25 },
   { name: "Jane", age: 30 },
   { name: "John", age: 30 },
];

orderBy(users, ["name", "age"], ["asc", "desc"]);
// [{ name: "Jane", age: 30 }, { name: "John", age: 30 }, { name: "John", age: 25 }]

uniqBy

Return the unique values in an array, optionally deduplicated by a specific key. When called without a key, uses Set semantics (identity/value equality).

import { uniqBy } from "@deebeetech/array-helper";

const users = [
   { name: "John", age: 25 },
   { name: "Jane", age: 30 },
   { name: "John", age: 30 },
];

uniqBy(users, "name");
// [{ name: "John", age: 25 }, { name: "Jane", age: 30 }]

uniqBy([1, 2, 3, 2, 1]);
// [1, 2, 3]
