@amor1006/lotide v1.0.2

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 @amor1006/lotide

Require it:

const _ = require('@amor1006/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• middle([array]): return the middle number in an array
• head([array]): return the first eleemnt in an array
• tail([array]): return the last eleemnt in an array
• assertArraysEqual([arr1],[arr2]): compare if two arrays are equal
• assertEqual(str1,str2): compare if two strings are equal
• assertObjectsEqual(obj1,obj2): compare if two objects are equal
• countOnly(str): It will return an object containing counts of everything that the input object listed.
• map(arr, callbackFn): return a new array based on the results of the callback function.
• takeUntil(arr, callbackFn): return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• findKey(obj, callbackFn): return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• countLetters(str): return a count of each of the letters in that sentence.
• letterPositions(str): return all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue(obj, value): It should scan the object and return the first key which contains the given value.
• eqObjects(obj1, obj2): take in two objects and returns true or false, based on a perfect match.
• without(arr, itemsToRemove): returns a new array without the itemsToRemove
• flatten(arr): returns a new array takes out every element wrapped inside an array
