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

npm install @eze1er/lotide

Require it:

const _ = require('@eze1er/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• head(): which returns the first item in the array.
• tail(): which returns the "tail" of an array: everything except for the first item (head) of the provided array.
• middle(): The middle function should return an array with only the middle element(s) of the provided array
• countOnly(): countOnly will be given an array and an object. It will return an object containing counts of everything that the input object listed.
• countLetters(): The function should take in a sentence (as a string) and then return a count of each of the letters in that sentence.

• letterPositions(): function letterPositions which will return all the indices (zero-based positions) in the string where each character is found.

• findKeyByValue(): function which takes in an object and a value. It should scan the object and return the first key which contains the given value

*map(array, callback): The function will return a new array based on the results of the callback function.

• takeUntil(array, callback): Function which will keep collecting items from a provided array until the callback provided returns a truthy value.

• findKey(obj, callback): Function which takes in an object and a callback. It should scan the object and return the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
