Lotide
A mini clone of the Lodash library.
Purpose
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 (dinopranjic) as part of my learnings at Lighthouse Labs.
Usage
Install it:
npm install @dinopranjic/lotide
Require it:
const _ = require('@dinopranjic/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation

: Takes in a string and returns an object containing all the letters in the string and how many times they occur. -
countOnly(allItems, itemsToRemove)
: takes in an array of items and an object listing items as true or false. Returns a new object containing all the items listed as true in the array and how many times they occur. -
eqArrays(firstArray, secondArray)
: takes in two arrays and returns true if they are the same or false if they are not the same. -
eqObjects(object1, object2)
: takes in two objects and returns true if they are the same or false if they are not the same. -
findKey(object, callback)
: takes in an object and a callback function. Returns a key according to the callback. -
findKeyByValue(object, value)
: takes in an object and a value. Returns a key with a value that matches the value input. -
flatten(array)
: takes in a two-dimensional array and returns a 'flattened' one-dimensional array. -
head(array)
: takes in an array and returns a new array containing the 'head' or first element. -
letterPositions(string)
: takes in a string and returns the index positions of each letter. -
map(array, callback)
: takes in an array and a callback function. Returns new modified array according to callback. -
middle(array)
: takes in an array. Returns a new array containing the middle element(s) of the array. -
tail(array)
: takes in an array. Returns a new array containing the 'tail' or every element but the first element. -
takeUntil(array, callback)
: takes in an array and callback function. Returns a new array containing elements up to, but not including, the first element to satisfy the callback function. -
without(source, itemsToRemove)
: takes in two arrays. Returns a new modified array with elements of the source array that did not match elments of the second array. -
assertEqual(actual, expected)
: takes in two primitive data types and console logs whether they are the same or not. -
assertArraysEqual(array1, array2)
: takes in two arrays and console logs whether they are the same or not. -
assertObjectsEqual(object1, object2)
: takes in two objects and console logs whether they are the same or not.
