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 @amrinder.singh/lotide

Require it:

const _ = require('@amrinder.singh/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): Assertion test for eqArrays function.
• assertEqual(actual, expected): Assertion test which compares actual input and expected input. Will not work with objects.
• assertObjectsEqual(object1, object2): Assertion test for eqObjects function.
• countLetters(string): Takes in a sentence or a string and returns an object containing all the letters and their count.
• countOnly(array, object): Iterates over the array and returns only keys which have the value true in the object.
• eqArrays(array1, array2): Compares two arrays and returns true if they contain the same values.
• eqObjects(object1, object2): Compares two objects and returns true if they have the same key/values.
• findKey(object, callback): Returns the first key in an object for which the callback returns a truthy value.
• findKeyByValue(object, value): Returns the key in an object, according to the value.
• flatten(array): Can take nested arrays as parameters and returns a single array with all elements.
• head(array): Returns the first element in an array.
• letterPositions(string): Takes in a word or sentence and returns an object which contains each letter and an array of letter positions based on index.
• map(array, callback): Returns an array with the callback function applied to each element.
• middle(array): Returns the middle value or values of an array.
• tail(array): Returns an array without its first element.
• takeUntil(array, callback): Iterates over the array until the conditions of the callback return a truthy value, and returns new array with all elements until.
• without(source, itemsToRemove): Removes array of items from source array and returns new array.
