Lotide
A mini clone of the Lodash library.
Summary
This repository contains the lotide project which built a mini library for the Lighthouse Labs Web Development Bootcamp.
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 @yuhaoyan/lotide
Require it:
const _ = require('@yuhaoyan/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Table of Contents
- assertEqual
- compare the two values it takes in and print out a message telling us if they match or not
- head
- returns the first item in the array
- tail
- returns the "tail" of an array: everything except for the first item (head) of the provided array
- eqArrays
- takes in two arrays and returns true or false, based on a perfect match
- assertArraysEqual
- take in two arrays and console.log an appropriate message to the console
- without
- return a subset of a given array, removing unwanted elements
- flatten
- take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array
- middle
- take in an array and return the middle-most element(s) of the given array
- countOnly
- be given an array and an object. It will return an object containing counts of everything that the input object listed
- countLetters
- take in a sentence (as a string) and then return a count of each of the letters in that sentence
- letterPositions
- return all the indices (zero-based positions) in the string where each character is found
- findKeyByValue
- takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined
- eqObjects
- take in two objects and returns true or false, based on a perfect match
- assertObjectsEqual
- take in two objects and console.log an appropriate message to the console
- map
- take in two arguments:
- An array to map
- A callback function
- The map function will return a new array based on the results of the callback function
- take in two arguments:
- takeUntil
- take in two parameters:
- The array to work with
- The callback (which Lodash calls "predicate")
- The function will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value
- take in two parameters:
- findKey
- takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined
