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 @beccasbizarreadventure/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual: compares two single-level arrays and logs a pass/fail assertion based on exact equivalency.
• assertEqual: compares two numbers or strings and logs a pass/fail assertion based on exact equivalency.
• assertObjectsEqual: compares two objects and logs a pass/fail assertion based on exact equivalency.
• countLetters: takes a string and counts the instance of each unique letter in the string.
• countOnly: takes an array of strings and an object and counts the instances of the true values identified in the object that are contained in the given array.
• eqArrays: compares two single-level arrays and returns 'true' or 'false' based on exact equivalency.
• eqObjects: compares two objects and returns 'true' or 'false' based on exact equivalency.
• findKey: takes an object and a callback function and returns the key of the first instance where the callback function returns a truthy value.
• findKeyByValue: takes and object and a value and returns the key of the first instance of the given value.
• flatten: creates a single-level array from a two-level array.
• head: returns the first value of an array.
• letterPositions: takes a string and returns the indexes of a specified letter in that string.
• map: takes an array and a callback function and returns a new array from the results of the callback function.
• middle: returns the middle value(s) of an array.
• tail: returns all values of an array, except the first value.
• takeUntil: takes an array and a callback function and pushes items into a new array until the callback function returns a truthy value.
• without: takes two single-level arrays, removes the items in array one that are common to array two, and returns a new array of the remaining items.
