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 @lilywhitford/lotide

Require it:

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

Call it:

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

• assertEqual(actual, expected): Compares two primitive types, printing out a pass/fail message to the console.
• assertObjectsEqual(actual, expected): Compares two obejcts, printing out a pass/fail message to the console.
• countLetters(sentence): Returns a count of each letter from a string.
• countOnly(allItems, itemsToCount): Returns counts for a specific subset from a collection of items.
• eqArrays(arr1, arr2): Compares two arrays for a perfect match.
• eqObjects(object1, object2): Returns true or false based on a perfect match from two objects.
• findKey(object, callback): Scans an object and returns the first key.
• findKeyByValue(object, value): Returns the first key which contains the given value from an object.
• flatten(array): Returns a singular array from a nested array.
• head(array): Retrieves the first element from an array.
• letterPositions(sentence): Returns all indices in a string where each character is found.
• middle(array): Returns the middle elements from a given array.
• tail(array): Retrieves every element except the head (first element) of an array.
• takeUntil(array, callback): Returns a slice of an array with elements taken from the beginning.
