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 @anneloes94/lotide

Require it:

const _ = require('@anneloes94/lotide');

Call it:

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


The following functions are currently implemented:

  • assertArraysEqual(array1, array2): logs whether two arrays are equal
  • assertEqual(actual, expected): checks two values to see if they are equal
  • assertObjectsEqual(actual, expected): logs whether two objects are equal
  • countLetters(sentence): creates an objects of letter keys and count values out of a sentence
  • countOnly(allItems, itemsToCount): filters out items to count out of an array of items and returns an object
  • eqArrays(arr1, arr2): compares two arrays and sees if they are equal
  • eqObjects(object1, object2): sees whether the keys and values of two objects are the same
  • findKey(object, callback): returns a key that has to be found in an object, or undefined if it is not present
  • findKeyByValue(object, inputValue): returns the first key in an object that matches the inputValue, or returns undefined
  • flatten(arrayOfArrays): flattens an array input that may exist of multiple arrays
  • head(array): returns the first (head) element of an array
  • letterPositions(sentence): returns an object of indices of letters in a sentence
  • map(array, callback): modifies an array with a callback function, returns a new array
  • middle(arr): takes the middle element(if length is odd) or elements (if length is even) of an array
  • tail(array): returns the tail of an array (all but first element)
  • takeUntil(array, callback): returns an array that stops when a callback condition has been met
  • without(source, itemsToRemove): returns an array that was filtered from another array
