@minzi123/lotide v1.1.3

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 @minzi123/lotide

Require it:

const _ = require('@minzi123/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual():Take in two arrays and console.log an appropriate message to the console.

• assertEqual(): Compare the two values it takes in and print out a message telling us if they match or not.

• assertObjectsEqual():Take in two objects and console.log an appropriate message to the console.

• countLetters():Take in a sentence (as a string) and then return a count of each of the letters in that sentence.

• countOnly():Take in a collection of items and return counts for a specific subset of those items.

• eqArrays():Takes in two arrays and returns true or false, based on a perfect match.

• eqObjects():Take in two objects and returns true or false, based on a perfect match.

• findKey():Takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.

• findKeyByValue():Takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.

• head(): Returns the first item in the array.

• letterPositions():Return all the indices (zero-based positions) in the string where each character is found.

• map(): Will take in two arguments: 1)An array to map, 2)A callback function, and return a new array based on the results of the callback function.

• middle():Take in an array and return the middle-most element(s) of the given array.

• tail():return an array of all elements except first.

• takeUntil():Return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.

• without(): Return a subset of a given array, removing unwanted elements.
