@kangerdrew/lotide v1.0.1

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 @kangerdrew/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): Returns the first element of an array.

• tail(array): Returns every element of the array except for the first element.

• middle(array): Returns the middle element of the array (within an array). If the length of an array is even, it will return two middle elements instead.

• countLetters(string): Returns the number of letters in the string input.

• countOnly(allItems, itemsToCount): Returns how many times a item specified in "itemsToCount" object input, is included in the allItems array input. Check the example commented out in the main script...

• eqArrays(ar1, ar2): Returns either true or false depending on whether the two arrays are equal or not.

• eqObjects(object1, object2): Returns either true or false depending on whether the two objects are equal or not.

• findKey(object, callback): Through the callback input, the function returns the key of an input object with a specified nested key value. See findKey.js script for commented out example...

• findKeyByValue(obj, inputKeyval): Returns a key from the input obj, by finding the one with a corresponding inputKeyval.

• flatten(array): Takes an array containing elements including nested arrays of elements, and return a "flattened" version of the array. Only works for one level of nesting.

• letterPositions(sentence): Takes a string input, and returns an object with keys that are the letters in the input string. The key values is an array of the index location of each letter.

• map(array, callback): Will return a new array based on the results of the callback function.

• takeUntil(array, callback): Will return a slice of the array with elements taken from the beginning. It should keep going until the callback/predicate returns a truthy value.

• without(array, remove): Will return a a new array, except the elements specified in "remove" input array will be removed.
