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 @charlielhl/lotide

Require it:

const _ = require('@charlielhl/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): takes an array and returns the first item in it
• tail(array): takes an array and returns a new array with everything except the first item
• middle(array): takes an array and returns the middle item of it as an array (1 item for odd and 2 items for even)
• assertArraysEqual(actual, expected): takes two arrays and returns a message corresponding to if they match or not
• assertEqual(actual, expected): takes two basic inputs and returns a message corresponding to if they match or not
• assertObjectsEqual(actual, expected): takes two objects and returns a message corresponding to if they match or not
• countLetters(sentence): takes a string and counts the amount of each letter present in it
• countOnly(allItems, itemsToCount): takes an array and an object and returns an object with only the specified inputs counted
• eqArrays(arr1, arr2): takes two arrays and returns a boolean corresponding to if they are equal or not
• eqObjects(object1, object2): takes two objects and returns a boolean corresponding to if they are equal or not
• findKey(object, callback): finds the first key of an object that matches the criteria created by the callback function
• findKeyByValue(object, value): returns an objects key that matches with the given value
• flatten(array): takes a nested array and returns a new, un-nested array
• letterPositions(sentence): returns an object of arrays showing the indices of each letter in a sentence
• map(array, callback): applies a given callback function to each item in an array and returns the result
• takeUntil(array, callback): loops through a given array until it reaches a condition stated by the callback function, which stops the loop, and returns what passed through thus far
• without(source, itemsToRemove): returns a new array based on the source array with things specified by the itemsToRemove array removed
