@samjanderson/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 @samjanderson/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head: returns the first item in an array
• tail: returns everything but the first item in an array
• middle: returns the middle element in an odd number array and the two middle elements in an even numbered array
• eqArrays: returns true if two arrays are equal
• without: returns a subset of a given array, removing unwanted elements
• takeUntil: this function will keep collecting items from a provided array until the callback provided returns a truthy value.
• map: consoles log true or false based on if our expected condition that we test meets our actual outcome
• letterPositions: this will return all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue: helps us search for a key on an object where its value matches a given value.
• findKey: scans an object and returns the first key for which the callback returns a truthy value. If no key is found, then it should return undefined.
• eqObjects: checks if two objects are equal and returns true or false
• countOnly: takes in a collection of items and return counts for a specific subset of those items
• countLetters: takes in a sentence (as a string) and then return a count of each of the letters in that sentence.
• assertObjectsEqual: checks to see if two objects are equal and logs a pass or fail
• assertEqual: checks to see if an expected outcome is equal to an actual outcome and logs a pas or fail
• assertArraysEqual: checks to see if two arrays are equal and console logs a pass or fail
