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 @krizvee/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(...): it returns the first item in the array
• middle(...): it returns the the middle element in an array if array length is greater than 2 else it returns empty array. Also in even case it returns middle two elements.
• tail(...): it returns all the item in the array except the first one
• assertEqual(...): this methode compares actual with expected parameters
• eqArrays(...): it return whether the two arrays are equal or not in a boolen format. It also works for only nesting of arrays.
• assertArraysEqual(...): it return the equality of two arrays with appropriate message. It also works for only nesting of arrays.
• without(...): it returnt he array without the second argument from the original array
• flatten(...): it will flatten the nested array into a flat array
• countOnly(...): it will count the presence of item within an array of strings based on the object specifying what to count
• countLetters(...): it should take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• letterPositions(...): it will return all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue(...): It will help us search for a key on an object where its value matches a given value.
• eqObjects(...): it return whether the two objects are equal or not in a boolen format. It also works for only nesting of objects.
• eqAssertObjects(...): it return the equality of two objects with appropriate message. It also works for only nesting of objects.
• takeUntil(...): it will return a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• map(...): it works similar to built-in mao function under javascript
• findKey(...): it 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.
