Lotide

Lotide is a mini clone of the Lodash Library to practice creating a personal npm package. It's like lodash, but without all that extra stuff. Just the things you need to start your project. Lotide is my first package I ever published.

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. I welcome any feedback!

Not all modules have had tests built for them, I plan to expand the tests further.

Usage

Install it:

npm install @mattseligman/lotide

Require it:

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

Call it:

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

Test it:

mocha test

Documentation

The following functions are currently implemented:

• head(array): Return an array with only the first value.
• tail(array): Return an array with only the end values (excluding the first entry)
• middle(array): Produces the middle value within an array.
• assertArrayEqual(array, array): Will produce a console log if arrays are True or False.
• assertEqual(string, string): Compares two strings and results in True or False
• assertObjectsEqual(object,object): Compares two objects and results in True or False.
• countLetters(string): Returns an object with the amount of letters contained.
• countOnly(array, object): Returns an object containing counts of everything that the input object listed.
• eqArrays(array,array): Compares two Arrays resulting in True or False.
• eqObjects(object, object): Compares two Objects resulting in True or False.
• findKey(object, key): Returns the key if found within the object.
• findKeyByValue(object, value): Returns the first key which contains the given value. If no key with that given value is found, then returns undefined.

• letterPositions(string): Return all the indices (zero-based positions) in the string where each character is found.
• map(array, callback): Returns a new array based on the results of the callback function.
