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 @m-arthell/lotide

Require it:

const _ = require('@m-arthell/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): Takes two arrays and compares them. Gives back a console.log of the result.
• assertEqual(actual, expected): takes in two values and compares them. Gives back a console.log of the result.
• assertObjectsEqual(actual, expected): Takes two objects and compares them. Gives back a console.log of the result.
• countLetters(string): Counts the amount of letters in a given string.
• countOnly(allItems, itemsToCount): Takes an array of strings, and an object specifying what to count. Returns the amount of times the specified items show up in the array.
• eqArrays(arr1, arr2): Takes in two arrays and returns true or false depending on whether they're equal or not.
• eqObjects(object1, object2): Takes in two objects and returns true or false depending on whether they're equal or not.
• findKey(obj, callback): Takes in an object and a callback that checks for something within said object, and returns the key if found.
• findKeyByValue(obj, content): Takes in an object and the content of a key, then returns the key that contains said content.
• flatten(array): Takes in an array containing arrays and return it as a single array.
• head(array): Takes in an array and returns the first element in it.
• letterPositions(string): Takes in a string and returns an object that lists the letters and their positions.
• map(array, callback): Takes in an array and a callback then returns an array based on the callback's specification.
• middle(array): Takes in an array and returns the middle most element/s.
• tail(array): Takes in an array and returns everything beyond the first element.
• takeUntil(array, callback): Takes in an array and callback that specifies a point to cut off. Returns an array that includes elements up until the element specified by the callback.
• without(array, toRemove): Takes in array and an array of elements to be removed from the first array. Returns a copy of the first array that excludes the elements specified in the second array.
