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 @ricardowgomes/lotide

Require it:

const lotide = require('@ricardowgomes/lotide');

Call it:

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

Documentation

The following functions are currently implemented:

• countLetters(str): Receives a string as an argument and return an object with the letterkey and number of times counted as value, that can be easily accessed with dot notation.

• countOnly(arr): Receives an array of strings and returns an object with the stringkey and the number of times counted as value, that can be easily accessed with dot notation.

• findKey(obj, callback): Receives an object and a callback-function define a criteria to return the first key based on the value of the object.

• findKeyByValue(obj, str): Receives an object and a string that returns the first key based on the value of the argument string. If the value is not in the object, it returns undefined.

• flatten(arr): Receives an array and if this array is nested (2D array), it returns a flatten array, in other words, an 1D array.

• head(arr): Receives an array and returns the head element of that array.

• map(arr, callback): Receives an array and a callback-function, the function returns the array with each element transformed based on function logic provided.

• middle(arr): Receives an array, if the array.length is even, it returns an array with the two middle elements, if is odd, it returns the single middle element.

• letterPositions(str): Receives a string as an argument and return an object with each letter as key and the index of each letter as value, that can be easily accessed with dot notation. If there is more than one of the same letter, the value of that letter is an array with all indexes.

• takeUntil(arr, callback): Receives an array and a callback-function, that returns the array with the elements until specific logic of the function.

• tail(arr): Receives an array as argument and returns the tail element of that array.
