@elhammir/lotide v1.0.0

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 @elhammir/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(array): retrieve the first element from the array
• tail(array): returns every element except the head (first element) of the array.
• eqArrays(actual, expected): returns true if two arrays are the same
• without(source,itemsToRemove ): This function should take in a source array and a itemsToRemove array. It should return a new array with only those elements from source that are not present in the itemsToRemove array.
• middle(actual ): will take in an array and return the middle-most element(s) of the given array.
• countOnly(allItems, itemsToCount ): Let's work together to implement countOnly. This function should take in a collection of items and return counts for a specific subset of those items.
• • countLetters(actual): The function should take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• • • letterpositions(sentence): will return all the indices (zero-based positions) in the string where each character is found.
• • • • findKeyByValue(actual, expected): will return all the indices (zero-based positions) in the string where each character is found.
• • • • • eqObjects(object1, object2): will return true if the objects are equal and false otherwise
• • • • • map(array, callback): 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.
• • • • • findKey(array, callback): 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.
