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 @nicodann/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• countLetters(string): Given a string it returns an object with keys corresonding to each different character in the string and values corresponding to how many times the key exists in the string.
• countOnly(array,object): Given an array of values and an object of keys and booleans it returns an) object containing the number of times 'true' keys exist in an array.
• findKey(object, callback): Given an object and a callback it returns the key in an object whose value matches the output of the callback.
• findKeyByValue(object, value): given an Object and a Value it returns the key that matches the value.
• flatten(array): Given an array of values, including arrays and n levels of nested arrays, it will output an array without nested arrays with the same values
• head(array): Given an array it returns the array containing the first value of an array.
• letterPositions('string'): Given a string it will return an object with each different character as keys and the number of time the character appears in the string, as values.
• map(array, callback): Given an array and a callback it passes each element through the callback and return an array of the results.
• middle(array): Given an array it returns the array containing the middle value, or values, of an array.
• tail(array or string): Given an array or string returns the array or string minus the first value.
• takeUntil(array, callback): Given an array and a callback it will pass each element through the callback in turn and return an array containing each element of the input array until the callback returns true.
• without(array1,array2): Given two arrays it will return the first array minus the elements in the second.
