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 @codefloww/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): This function compares two arrays to check if they are equal in length and element and returns true or false
• assertEqual(actual, expected): checks if the actual value matches expected value.
• assertObjectsEqual(obj1, obj2): compares two objects to see if they are equal in nature and returns true or false
• countLetters(string): returns an object where the key is a letter and the value is the count
• countOnly(array, itemsToCount): returns an specific items in an array and returns the count of an item in an object
• eqArrays(arr1, arr2): compares two arrays to check if they are exactly equal. Returns true or false
• eqObjects(obj1, obj2): compares two objects and returns true if they are equal
• findKey(obj1, callback): returns the first key that fulfils the condition set by the callback
• findKeyByValue(obj, value): returns the key in an object that matches the value that coorespond to it
• flatten(array): combines array with another array to create a single array. Returns a single flattened array
• head(array): returns the first element of the array
• letterPositions(string): returns the position of each letter in a provided string. Each key being a letter and value being an array of indices
• map(arr, callback): returns a new array that match the same length as the original and apply whatever is done in the callback function
• middle(array): returns the middle element or elements of the array as a new array
• tail(array): returns all elements of the array except the first element
• takeUntil(arr, callback): returns a new array with elements from the original into the callback function returns true
• without(arr, itemsToRemove): returns a new array excluding the specified items
