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 @tonisam/lotide

Require it:

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

Call it:

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

• countLetters(): take in a sentence (as a string) and then return a count of each of the letters in that sentence
• countOnly(): take in a collection of items and return counts for a specific subset of those items
• findKey(): takes in an object and a callback,scans the object and returns the first key for which the callback returns a truthy value.
• findKeyByValue(): takes in an object and a value, scans the object and return the first key which contains the given value.
• letterPositions(): returns all the indices in a string where each character is found
• map(): take in an array to map and a callback function, and will return a new array based on the results of the callback function.
• takeUntil(): keeps collecting items from a provided array until the callback provided returns a truthy value.
