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.

Install it:

npm install @gascon-m/lotide

Require it:

const _ = require('@gascon-m/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head : returns the first item of an array
• tail : returns all but the first item of an array
• middle : returns the middle item of the array, if the array is of even length, returns two items
• assertArraysEqual : formats a proper answer after using eqArrays
• assertEqual : check if two items are equal, does not work on arrays or objects (see assertArraysEqual or assertObjectEqual)
• assertObjectEqual : formats a proper answer after using eqObjects
• countLetters : count the letters in a string
• countOnly : counts the occurence of a specified item in an array of strings
• eqArrays: checks if two arrays are equal
• eqObjects : checks if two objects are equal
• findKey : returns the value with the specified key
• findKeyByValue : returns the key with the specified value
• flatten : returns a multiple-level array as a single level array
• letterPositions : takes a string and returns an object with letters as keys and values are the index at which the letters appear
• maps : accepts an array and a callback function and returns what was asked of the callback function
• takeUntil: accepts an array and a callback function. Returns an array with all the values until the value of the callback function is reached.
• without : accepts an array and an item. Returns the array with the specified item removed from it.
