@devhan1207/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 @devhan1207/lotide

Require it:

const _ = require('@devhan1207/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: This function takes two arrays as input and prints assertion passed if two arrays are the same and assertion failed if not.
• assertEqual: This function takes and compares the two values which are primitive types (like numbers and strings), and print out a message telling us if they match or not.
• assertObjectsEqual: This function takes in two objects and print out a message telling us if they match or not.
• countLetters: This function takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly: This function takes in a collection of items and return counts for a specific subset of those items.
• eqAttays: This function takes in two arrays and returns true or false, based on a perfect match.
• eqObjects: This function takes in two objects and returns true or false, based on a perfect match.
• findKey: This function takes in an object and a callback. It scans the object and return the first key for which the callback returns a truthy value. If no key is found, then it returns undefined.
• findKeyByValue: This function takes in an object and a value. It scans the object and return the first key which contains the given value. If no key with that given value is found, then it returns undefined.
• flatten: This function takes an array and unnest the array if nested.
• head: This function takes an array and returns the first element in the array.
• index: This exports three functions(head,tail,middle) simultaneously.
• letterPositions: This function takes in a sentence (as a string) and then return all the indices (zero-based positions) in the string where each character is found.
• map: This function takes an array and function to map the array. It returns a mapped array.
• middle: This function takes in an array and return the middle-most element(s) of the given array.
• tail: This function takes an array and returns every element except the head (first element) of the array.
• takeUntil: This function takes an array and function returns the array where its elements are deleted when the callback function returns false.
• without: This function takes in a source array and a itemsToRemove array. It should return a new array with only those elements from source that are not present in the itemsToRemove array.
