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.

Install it:

npm install @leungcnie/lotide

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

Call it:

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

The following functions are currently implemented:

• head(array): returns the head of an array
• tail(array): returns the tail of an array
• middle(array): returns the middle element(s) of an array
• assertArraysEqual(arr1, arr2): asserts whether 2 arrays are equal
• assertEqual(actual, expected): asserts whether values are equal
• eqArrays(arr1, arr2): returns true if 2 arrays are equal, else return false
• flatten(array): flattens an array of nested arrays into a single array
• countOnly(allItems, itemsToCount): looks through an array allItems and returns an object of counts of only the items specified in itemsToCount
• letterPositions(string): returns the index of each character in a string
• findKeyByValue(obj, val): returns key that matches the value val in a given object obj
• eqObjects(obj1, obj2): returns true if 2 objects are equal, else return false
• assertObjectsEqual(obj1, obj2): asserts whether 2 objects are equal
• countLetters(string): returns an object of each letter in a string and their respective number of occurences
• findKey(obj, callback): returns key in object obj that satisfies the callback function
• map(array, callback): returns the result of applying the callback function to the array
• takeUntil(arr, callback): returns an array of arr's elements up until the element passed into the callback returns true
• without(source, itemsToRemove): returns a subset of a given array, removing unwanted elements
