eode

Eode

Eode is an amazing, hybrid, JavaScript package. It includes advanced functions for arrays and objects that lodash doesn't have!

Installation

npm i eode

Usage

CJS

const _ = require('eode')

ESM

import _ from "eode"

Examples

Eode offers the powerful _.must function. It allows dynamic filtration and distillation of arrays of objects. More functions will be added to eode in the future, but some of the best are shown below.
