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 @afreeda/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertEqual(value1, value2): logs to the console whether two given values are the same
• head(array): returns the first element of a given array
• tail(array): returns every element except the first element in a given array in a form of an array
• middle(array): returns an array of the middle elements of a given array
• eqArrays(arr1, arr2): checks if two given arrays are equal
• assertArraysEqual(arr1, arr2): assertion to check if two arrays are equal based on eqArrays()
• without(arr, itemsToRemove): when given an original array and an array of items to be removed, returns a modified original array without elements that were removed
• flatten(array): when given a nested array, returns a 1 dimensional array
• countOnly(allItems, itemsToCount): returns the counts for a specific subset of those items in a given array
• countLetters(string): returns an object of the number of times a character appears in a given string
• letterPositions(sentence): returns an object with array values of the index number of each character in a given string
• findKeyByValue(object, value): returns the key when given a value corresponding to that key
• eqObjects(obj1, obj2): checks for equality of given objects
• assertObjectsEqual(obj1, obj2): assertion to check for object equality using eqObects()
• map(array, callback): given an array and a callback, the function will return a modified array based on the condition of the callback
• takeUntil(array, callback): given an array and a callback, returns a new array of items up until a particular condition is met
• findKey(object, callback): given an object and callback, the function will return the first key associated with the value from the callback
