@leeseancw/lotide v1.0.1

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 @leeseancw/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(arr1, arr2): assertion function that compares 2 arrays
• assertEqual(actual, expected): assertion function that compares 2 primitives
• assertObjectsEqual(obj1, obj2): assertion function that compares 2 objects (which are not arrays)
• countLetters(sentence): function that takes in a string and catalogues each instance of each unique character
• countOnly(allItems, itemsToCount): function that counts for specific elements listed in itemsToCount in allItems
• eqArrays(arr1, arr2): function that checks if 2 arrays are absolutely identical
• eqObjects(object1, object2): function that checks if 2 objects (not arrays) are absolutely identical
• findKey(object, callback): function that scans the object and return the first key for which the callback returns a truthy value.
• findKeyByValue(obj, val): function that takes in an object and a value. It should scan the object and return the first key which contains the given value.
• flatten(arr): a duplicate function of the built-in .flat()
• head(arr): function that returns the first element of an array
• letterPosition(sentence): functoin that returns all the indices (zero-based positions) in the string where each character is found.
• map(array, callback): a duplicate function of the built-in .map()
• middle(arr): function that takes an array and returns the middle (or 2 middle) value in an array
• tail(arr): function that returns an array without the first element
• takeUntil(array, callback): function that takes an array and returns a new array with elements up to when the callback function returns truthy
• without(source, itemsToRemove): a similar function to the built-in .filter()
