a mini clone of lodash

Usage no npm install needed!

<script type="module">
  import chonie1Lotide from 'https://cdn.skypack.dev/@chonie1/lotide';



A mini clone of the Lodash library.


BEWARE: This library was published for learning purposes. It is not intended for use in production-grade software.

This project was created and published by me as part of my learnings at Lighthouse Labs.


Install it:

npm install @chonie1/lotide

Require it:

const _ = require('@chonie1/lotide');

Call it:

const results = _.tail([1, 2, 3]) // => [2, 3]


The following functions are currently implemented:

  • countLetters(str): counts the number of occurences of each character given a string
  • countOnly(allitems, itemsToCount): given an allItems array, and an itemsToCount object, returns an object with the value true/false if the item in itemsToCount is present in allItems
  • eqArrays(arr1, arr2): returns true if two arrays are equal else false
  • eqObjects(obj1, obj2): returns true if two objects are equal else false
  • findKey(obj, callback): returns a key in the obj given a callback function with a conditional
  • findKeyByValue(obj, val): returns the first key in the obj that matches the val input
  • flatten(arr): flattens a nested array
  • head(arr): returns the first element of the array
  • letterPositions(str): returns an array of indices for each char in the string
  • map(arr, callback): changes the array given a callback function
  • middle(arr): returns the middle element of the array (returns an array of two numbers if the input array length is even)
  • tail(arr): removes the first element of the array
  • tailUntil(arr, callback): returns part of the array depending on the callback conditional
  • without(source, itemsToRemove): removes items in source given an itemsToRemove array
