@luc-ky/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 @luc-ky/lotide

Require it:

const _ = require('@luc-ky/lotide');

Call it:

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

The following functions are currently implemented:

assertArraysEqual: asserts two arrays are equal
assertEqual: console logs if assertion is true or false
assertObjectsEqual: asserting two objects are equal
countLetters(string): returns an object with the count of each of the letters in the string
countOnly(array, object): returns counts for a subset of those items
eqArrays(array, array): compares two arrays for a perfect match
eqObjects(object, object): returns if two objects are perfect match
findKey(object, callback): returns the first key which the callback returns a truthy value
findKeyByValue(object, value): scans the object and returns the first key which contains the given value
flatten(array): returns a flattened array
head(array): returns the first element of an array
letterPositions(string): takes a sentence and returns the indices where each letter is found
map(array, callback): maps a new array based on the results of the callback function
middle(array): returns the middle elements of an array
tail(array): returns all elements of an array except for the first
takeUntil(array, callback): takes an array and a callback and returns a new array
