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 @lloydgerry/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1,array2): takes in two arrays and compares them in JSON as strings to see if they are equal, logs to screen.
• assertEqual(actual,expected): takes in two primitives as variables and compares to see if they are equal.
• assertObjectsEqual(object1,object2): compares two objects to see if they are equal.
• countLetters(stringCounted): input a string and returns an object with keys as letters, and their subsequent count as key value.
• countOnly(allItems,itemsToCount): inputs two arrays, and returns an object. Keys are items that match from both arraysys and the count matching values as the key value.
• eqArrays(array1,array2): using JSON stringify to compare two arrays, a match is true.
• eqObjects(object1,object2): compares two objects to see if they are equal.
• findKey(object,callback): takes in an object and a callback function, the function should be the the key we would like to return(find); finds first only.
• head(array): inputs an array and finds the value if the first(zero) index
• letterPositions(sentence): inputs a string and returns an object. Keys are the letters, and the key values are the count of those letters in string.
• map(array,callback): inputs an array and a callback function and returns an array.
• middle(arrayMid): inputs array, and finds the middle value (odd) or middle two values (even) as a new array.
• tail(array): inputs an array and returns a new array splicing out first index.
• takeUntil(array, callback): inputs an array and a callback function, returns new array using the callback function as a cutoff point.
• without(sourceArr,removeItemsArr): takes in two arrays, using the second(removeItemsArr) as items to remove from first array, returns new array.
