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 @vanessalinda/lotide
Require it:
const _ = require('@vanessalinda/lotide');
Call it:
const results = _.tail([1, 2, 3]) // => [2, 3]
Documentation
The following functions are currently implemented:
head()
: retrieves the first item in the array.tail()
: retrieves every element except the head (first element) of the array.assertEqual()
: compares the two values it takes in and print out a message telling us if they match or not.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()
: returns a subset of a given array, removing unwanted elements.flatten()
: takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.middle()
: takes in an array and return the middle-most element(s) of the given array.countOnly()
: takes in a collection of items and return counts for a specific subset of those items.countLetters()
: takes in a sentence (as a string) and then return a count of each of the letters in that sentence.letterPositions()
: returns 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()
: takes in two objects and console.log an appropriate message to the console.map()
: creates a new array populated with the results of calling a provided function on every element in the calling array.takeUntil()
: returns a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.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.
