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 as part of my learnings at Lighthouse Labs.
Usage
Install it:
npm install @sjung/lotide
Require it:
const _ = require('@sjung/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
-
assertArraysEqual(arrayOne, arrayTwo): checks if 2 arrays are same. Console.log an appropriate message based on whether they are equal. -
assertEqual(dataOne, dataTwo): checks if 2 pieces of data are same. Must be one of javascript's 6 data types. Console.log an appropriate message based on whether they are equal. -
assertObjectEqual(objectOne, objectTwo): checks if 2 objects are same. Console.log an appropriate message based on whether they are equal. -
countLetters(data): checks how many times each character/ number occurs in the input (not including spaces). Returns an object with each letter as keys and the value is the number of times it occured. -
countOnly(array, data): checks how many times the data you inputted (string, number, etc) occurs in the inputted array. Returns a number with how many times it occured. -
eqArrays(arrayOne, arrayTwo): checks if 2 arrays are same. Returns True or False. -
eqObjects(objectOne, objectTwo): checks if 2 objects are same. Returns True or False. -
findKey(object, callback): checks for first value which matches callback criteria. Returns that key. -
findByKeyValue(object, data): checks for first value which matches data we inputted. Returns that key. -
flatten(array): if there are nested arrays in input array, removes all nested arrays and lists elements in that array. Returns array with no nested arrays. -
head(array): inputs an array. returns first element of that array (array[0]). -
letterPositions(data): inputs some data (string, number, etc). returns an object with each character as keys. the value of the keys is an array with each index that character occurs. -
map(array): inputs an array and callback function. returns new array with the callback function applied to each element of the input array -
middle(array): inputs an array. returns array with the middle index element. For arrays with even number of elements, returns array containing middle 2 elements. -
tail(array): inputs an array. returns same array minus first element of that array (array[0]). -
takeUntil(array, callback): inputs an array and callback criteria. returns same array until the element that the callback criteria is met. -
without(array, data): inputs an array and data. Returns array with any elements of the array === inputted data removed.
