@caboma/lotide NPM

Lotide

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 caboma/lotide

Require it:

const _ = require('caboma/lotide');

Call it:

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

The following functions are currently implemented:

assertArraysEqual: which will take in two arrays and console.log an appropriate message to the console
assertEqual: implement custom assertEqual function to help us test code
assertObjectsEqual: function which easily test functions that return objects
countLetters: take in a sentence (as a string) and then return a count of each of the letters
countOnly: take in a collection of items and return counts for a specific subset of those items
eqArrays: takes in two arrays and returns true or false
eqObjects: take in two objects and returns true or false, based on a perfect match
findKey: which 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
findKeyByValue: takes in an object and a value , scan the object and return the first key which contains the given value
head: function for arrays to retrieve the first element from the array
letterPositions: which will return all the indices (zero-based positions) in the string where each character is found
map: will return a new array based on the results of the callback function
middle: will take in an array and return the middle-most element(s) of the given array
tail: function for arrays to retrieve the last element from the array
takeUntil: will keep collecting items from a provided array until the callback provided returns a truthy value
without: will return a subset of a given array, removing unwanted elements
