@lenilsamuel/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 @lenilsamuel/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• eqArrays: Function that checks whether two arrays are equal.
• eqObjects: Function that checks whether two objects are equal.
• head: Function that returns the first value of an array.
• tail: Function that returns the last value of an array. Function does not change the original (provided) array
• flatten: Function that takes in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• assertEqual: Simple test function that compares two values and checks whether they are strictly equal.
• assertArraysEqual: Simple test function that compares two arrays and checks whether they are strictly equal using the eqArrays function.
• without: Function that removes an unwanted element (provided) and returns a subset of the array without the provided unwanted element.
• middle: Function that returns the middle element of an array. If the array is even-numbered, it returns an array with the two elements in the middle.
• countOnly: Function that takes in a collection of items and return counts for a specific subset of those items that are provided.
• countLetters: Function that takes in a sentence as a string and returns a count of each letter in the sentence.
• letterPositions: Function that returns all the indices in a given string where each character is found.
• findKeyByValue: Function that searches for a key on an object where its value matches a given value.
• assertObjectsEqual: Simple test function that compares two objects and checks whether they are equal.
• assertObjectsEqual: Simple test function that compares two objects and checks whether they are equal.
• takeUntil: Function that accepts and array and a callback function and returns a slice of the array including all elements until the passed in 'filter' value via the callback.
• findKey: Function that takes in an object and a callback and checks the object. It returns the first key for which the callback returns a truthy value. If no key is found, it returns undefined.
