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 @BDeWitt-Cohen/lotide

Require it:

const _ = require('@BDeWitt-Cohen/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(...): takes single array as argument and returns index[0]
• tail(...): takes single array as argument and returns everything after index[0] as a new array
• middle(...): takes single array as argument and returns middle index for odd length array, and middle two indexes for even length array
• assertArraysEqual(arr1, arr2): takes two arguments of arrays and then says whether or not they are equal
• assertEqual(...): takes two primitive data type arguments and then says whether or not they are equal
• assertObjectsEqual(...): takes two arguments of objects and then says whether or not they are equal
• countLetters(...): takes a string argument, counts the instances of each letter and returns an object with the count
• countOnly(...): takes an argument of an array and counts the number of returns the count of items
• eqArrays,(...): takes two arguments of arrays and then says whether or not they are equal
• eqObjects(...): takes two arguments of objects and then says whether or not they are equal
• findKey(...): takes two arguments, an object and a helper function and returns a key from the object based on the value input into the helper function
• findKeyByValue(...): takes two arguments, an object and a value and returns the key with that value
• flatten(...): takes an array as an argument, if there's a nested array it will return as a single level array
• letterPosition(...): takes a string as an argument and returns an object with each letter from the string as keys and their index position (as an array) as the values
• map(...): takes two arguments, as array and a callback function, the callback returns index[0] of the words
• takeUntil(...): takes two arguments, an array and callback function, callback is designed to stop at odd number, returns array until the odd number
• without(...): takes two array arguments and return the first array with any matches from the second array removed
