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 @marcelama/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• function assertArraysEqual(): function for asserting that two arrays are equal
• function assertEqual(): will compare the two values it takes in and print out a message telling us if they match or not
• function assertObjectsEqual(): takes in two objects and console.log an appropriate message to the console.
• function without(): will return a subset of a given array, removing unwanted elements
• function head(): return head of array
• function taild(): return tail of array
• function middled(): return the middle-most element(s) of the given array
• function countLettersd(): takes in a sentence (as a string) and then return a count of each of the letters in that sentence
• function countOnly(): takes in a collection of items and return counts for a specific subset of those items
• function eqArrays(): takes in two arrays and returns true or false, based on a perfect match
• function eqObjects(): takes in two objects and returns true or false, based on a perfect match
• function findKey(): takes in an object and a callback, scans the object and return the first key for which the callback returns a truthy value
• function findKeyByValue(): takes in an object and a value, scans the object and return the first key which contains the given value
• function flatten(): takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• function letterPositions(): returns all the indices (zero-based positions) in the string where each character is found
• function map(): returns a new array based on the results of the callback function
• function takeUntil(): will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
