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 @emikeke/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head: returns first element in an array
• tail: returns everything except first element in an array
• middle: returns middle-most element(s) in an array
• assertArraysEqual: returns T/F after comparing actual with expected value (supports non primitive types)
• assertEqual: compares actual with expected value (doesn't support objects & array)
• assertObjectsEqual: returns T/F after comparing actual with expected value (supports objects)
• countLetters: returns a count of each of the letters in a string
• countOnly: returns counts for a specific subset of items
• eqArrays: compares actual with expected value (supports arrays)
• eqObjects: takes 2 objects, returns T/F based on a perfect match
• findKey: returns the first key for which the callback returns a truthy value if no key i
• findKeyByValue: returns the first key with contains the given value
• letterPositions: return all the indicies in the string where each character is found
• map: returns a new array based on the results of the callback function
• takeUntil: returns a slice of the array with elements taken from the beginning and keeps going until the callback/predicate returns a truthy value
• without: returns a subset of a given array, removing unwanted elements
