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 @hoshaun/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): Returns true if arrays arr1 and arr2 are the same
• assertEqual(actual, expected): Returns true if actual === expected
• assertObjectsEqual(actual, expected): Returns true if two objects are the same
• countLetters(sentence): Returns an object containing key-value pairs counting the number of occurrences of each letter in a sentence
• countOnly(allItems, itemsToCount): Returns an object containing the number of occurrences of each item in itemsToCount that occurs in allItems
• eqArrays(arr1, arr2): Recursively inspects two input arrays and returns true if they are the same
• eqObjects(object1, object2): Recursively inspects two input objects and returns true if they are the same
• findKey(obj, callback): Returns the first key found in obj that satisfies callback(obj.key)
• findKeyByValue(obj, val): Returns the first key found in obj where obj.key === val
• flatten(arr): Returns a new array by flattening arr
• head(array): Returns the head of array
• letterPositions(sentence): Returns an object containing key-value pairs where keys are the letters in sentence and values are an array containing the indices where each letter appears in the sentence
• map(array, callback): Returns a new array containing the values modified by mapping input array using callback function
• middle(arr): Returns the middle elements of arr
• tail(array): Returns the tail of array
• takeUntil(array, callback): Returns a new array containing the items in array up until the callback condition is satisfied
• without(source, itemsToRemove): Returns a new array containing the items in source excluding the items in itemsToRemove
