@gracewxt/lotide v1.0.0

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 @gracewxt/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(): a function for asserting that two arrays are equal
• assertEqual(): a function that compare the two values it takes in and print out a message telling us if they match or not
• assertObjectsEqual(): A function that takes in two objects and log an appropriate message (assertion) to the console.
• countLetters(): A function that takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly(): a function that when given an array and an object, it will return an object containing counts of everything that the input object listed.
• eqArrays(): a function that compares two arrays and returns a boolean
• eqObjects(): A funciton that takes in two objects and returns true or false, based on a perfect match.
• findKey(): A function that will scan the object and return the first key which contains the given value. Return undefined if no key with that given value is found.
• findKeyByValue(): A function that scan the value of each key in an object, and return the first key for which the callback returns a truthy value
• head(): a function that returns the first element in an array
• letterPositions(): a function which will return all the indices (zero-based positions) in the string where each character is found.
• map(): A map function that will return a new array based on the results of the callback function.
• middle(): a function that takes in an array and return the middle-most element(s) of the given array.
• tail(): a function that returns the tail of an array: everything except for the first item (head) of the provided array, without modifying the array passed in
• takeUntil(): A function that return a slice of the given array with elements taken from begining, until the callback returns a truthy value
• without(): a function that returns a subset of a given array, removing unwanted elements. Not modifying the original array.
