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 @aolvera/lotide

Require it:

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

Call it:

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

• countLetters(string): returns a count of each letter in the string.
• countOnly(array, object): returns counts for the items conatined in the input object that exist in the input array of strings.
• eqArrays(array1, array2): returns true if both arrays match perfectly or false if they do not.
• eqObjects(object1, object2): returns true if both objects match perfectly or false if they do not.
• findKey(object, function): returns the first object key for which the callback function returns a truthy value.
• findKeyByValue(object, value): returns the first object key for which that contains the given value.
• flatten(array): returns a flattened version of an array where all the nested arrays are removed and their elements added to the first-level array.
• letterPositions(string): returns an object containg lists of the indices in the string where each character is found.
• map(array, function): returns a new array based on the results of the callback function.
• takeUntil(array, function): returns a slice of the array starting from the begining, and ending when the callback function returns a truthy value.
• without(array1, array2): returns a new array with only the elements from array1 that are not present in array2.
