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 @navycuda/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

Please note that the majority of the unit testing was not converted from simple functions to mocha/chai.

• head([]) : Returns the first element of an array.
• tail([]) : Returns an array with everything except the first element.
• middle([]) : Returns an array with either one or two elements from the middle.
• countLetters('') : Returns an object with a count of all the characters excluding spaces.
• countOnly([], {}) : Counts the number of instances a key with the value of true exists within the supplied array.
• letterPositions('') : Returns an index of all the characters and an array of their positions within the string.
• eqArrays([],[]) : (x,y) => eqValue(x,y)
• eqObjects({},{}) : (x,y) => eqValue(x,y)
• eqValue(any,any) : Universal, recursive function for compairing values.
• flatten(array) : Flattens nested arrays into one flat array.
• findKey({},()=>{}) : Searches an object for a key using a callback function.
• map([],()=>{}) : Does work to array items according to the callback.
• findKeyByValue({},'') : Finds an object key by a search value
• without([],[]) : Removes elements from the first array if they exist in the second. Current implementation only supports primatives.
• takeUntil([],()=>{}) : Builds an array up until the callback is satisfied.
• outputToConsole(err,any) : Used to output simple things to the console.
• getRandomAlphanumericString(length) : Generates a random alphanumeric string to length.
• circularNumbers(position, change, limit) : Advances or Retards position by change within the limit, reseting to opposite value at extents.
• makeStringSafe(string, safeString) : Rebuilds strings with only the characters available in safeString
