@zeyneppkaya/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 @zeyneppkaya/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• tail(...): The tail function prints out every element except the head (first element) of the array.
• middle(...): Function will take in an array and return the middle-most element(s) of the given array.
• findkey(...): Function 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.
• head(...): Gets the first element of an array.
• takeUntil(...): Function 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.
• assertArraysEqual(...): Function will take in two arrays and console.log an appropriate message to the console.
• assertEqual(...): Assertion function prints out a colourful and therefore easy to read message in both success and failure scenarios for our codes.
• assertObjectsEqual(...): Function will take in two objects and console.log an appropriate message to the console.
• countLetters(...): The function will take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• countOnly(...): This function will take in a collection of items and return counts for a specific subset of those items.
• eqArrays: Function that can compare two arrays for a perfect match.
• eqObjects(...): Function will take in two objects and returns true or false, based on a perfect match.
• findKeyByValue(...): Function takes in an object and a value. It scans the object and return the first key which contains the given value.
• letterPositions(...): Function will return all the indices (zero-based positions) in the string where each character is found.
• map(...): Function will take in two arguments: An array to map and a callback function. The map function will return a new array based on the results of the callback function.
• without(...): Function will return a subset of a given array, removing unwanted elements.
