@r.flores/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 @r.flores/lotide

Require it:

const _ = require('@r.flores/lotide');

Call it:

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

The following functions are currently implemented:

head(array): returns the first element in an array
tail(array): returns an array with its first element removed
middle(array): returns the middle index of an odd array or the two in the middle when the array is even
without(array1, array2): given two arrays, elements of the second array are removed from the first array and returns the first array less those elements
takeUntil(array1, array2): pushes elements from one array to another from the head until it reaches the element provided as the second array argument
map(array): takes the first index of every element in the array and returns it in a new array
letterPositions(string): returns an object with letter keys that contain the value/values of the index/indices of that letter in the string
findKey(object, callback): returns the key of a given object using a value belonging to an object that is contained in the object paired to the key
findKeyByValue(object, value): returns the key of a given object given its value
countOnly(array, object): takes an array and an object containing the list of things to be counted in the array. It returns an object that lists the amount of times the things that had to be counted appeared in the array as key value pairs
countLetters(string): returns an object with a list of key value pairs containing letters and how many times it appeared in the string
