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 @aidanmiddleton/lotide

Require it:

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

Call it:

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


The following functions are currently implemented:

  • head: removes the last item of an array
  • tail: removes the first item in an array
  • middle: returns the middle point value of an array. if it has an even number, it returns the middle 2 values
  • assertEqual: checks if pieces of data are equal, compares an expected to an actual
  • assertObjectsEqual: checks if two objects are equal, compares an expected to an actual
  • countLetters: counts the letters in a string
  • countOnly: counts all of a particular string in a list of strings
  • eqArrays: checks if two arrays are equivalent
  • eqObjects: checks if two objects are equivalent
  • findKey: finds a paerticular key in an object
  • findKeyByValue: finds the name of a key based on a given value
  • flatten: removes all nested arrays, and brings contents into single array
  • letterPositions: finds letter at a specified index
  • map: runs a given callback function on every item of the array
  • takeUntil:
  • assertArraysEqual: asserts that an expected array is equal to the actual
  • without: returns a new array that is missing whatever values you specified to be removed.
