1.0.0 • Public • Published


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 @james-truong as part of my learnings at Lighthouse Labs.


Install it:

npm install @james-truong/lotide

Require it:

const _ = require('@james-truong/lotide');

Call it:

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


The following functions are currently implemented:

  • assertArraysEqual(arr1, arr2): Logs a message to show whether 2 arrays match.
  • assertEqual(x,y): Logs a message to show whether 2 primary objects match.
  • assertObjectsEqual(Obj1, Obj2): Logs a message to show whether 2 objects match.
  • countLetters(string): returns the count of each letter of the string with an Object format.
  • countOnly(array, itemstoLookfor): searches through the array and looks for itemsToLookFor. Returns an object with the new counts.
  • eqObjects(obj1, obj2): compares 2 objects and returns true if they're equal.
  • eqArrays(arr1,arr2): compare 2 arrays and return true if they're equal.
  • findKey(obj1, callback): returns the first key which matches the value which is given by the callback.
  • findKeyByValue(object, value): returns the first key which matches the value. (This is with no callback function).
  • flatten(array): Takes in a potentially nested array and spreads it to a single-nested array.
  • head(array): returns the front of the array.
  • letterPositions(sentence): returns an object that contains the letters (key) and index positions (value) of the sentence
  • map(array, callback): takes in two arguments 1) array to map and 2) callback function (when predicate is met) should return the altered array
  • middle(array): returns a new array with the middle index value/s of the original array
  • tail(array): returns a new array without the first index value of the original array
  • takeUntil(array, callback): takes a slice of an array with index values taken from the beginning until callback/predicate returns a truthy value
  • without(source, itemsToRemove): returns an array without the specified items
