# Lotide A mini clone of the [Lodash](https://lodash.com) 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 @b1u3too/lotide` **Require it:** `const _ = require('@b1u3too/lotide');` **Call it:** `const results = _.tail([1, 2, 3]) // => [2, 3]` ## Documentation The following functions are currently implemented: * `assertArraysEqual` : archived for review, do not use - visual console logger of assertions about arrays * `assertEqual` : archived for review, do not use - visual console logger of assertions about primitive datatypes * `assertObjectsEqual` : archived for review, do not use - visual console logger of assertions about objects * `countLetters` : return object containing summary of how often each letter in a provided string appears * `countOnly` : return object summarizing how often specified keys appear in provided object * `eqArrays` : check that two provided arrays are strictly equivalent -- recursive handling of nested arrays * `eqObjects` : check that two provided objects are strictly equivalent -- recursive handling of nested objects * `findKey` : return key of the first value in provided object to pass provided callback function test * `findKeyByValue` : return key of the last value matching provided value * `flatten` : return 1D array version of provided array containing arrays * `head` : return the first element of a provided array * `letterPositions` : return an object reporting on letters used and all index positions they appear in for a given input string * `map` : array.prototype.map weak clone -- apply callback function to each element of a given array, returning a new array * `middle` : return the middle element(s) of a provided array * `takeUntil` : return a slice of an array from the beginning, until the first element that passes provided callback test * `tail` : return all but the first element of a provided array * `without` : take in a source array, and an array listing what not to pass through, and return a new array _without_ those elements!
