@solenedel/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 @solenedel/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head(...): returns the first item in the array.
• tail(...): returns the "tail" of an array (everything except for the first item (head) of the provided array).
• middle(...): take in an array and return the middle-most element(s) of the given array.
• countLetters(...): take in a sentence (as a string) and then return a count of each of the letters in that sentence.
• without(...): return a subset of a given array, removing unwanted elements.
• flatten(...): take in an array containing elements including nested arrays of elements, and return a "flattened" version of the array.
• letterPositions(...): return all the indices (zero-based positions) in the string where each character is found.
• findKeyByValue(...): takes in an object and a value. It should scan the object and return the first key which contains the given value. If no key with that given value is found, then it should return undefined.
• eqObjects(...): take in two objects and returns true or false, based on a perfect match.
• assertObjectsEqual(...): take in two objects and console.log an appropriate message to the console.
• takeUntil(...): keep collecting items from a provided array until the callback provided returns a truthy value.
• findKey(...): 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. If no key is found, then it should return undefined.
• assertEqual(...): take in two values and assert whether or not they are equal.
• eqArrays(...): takes in two arrays and returns true or false, based on a perfect match.
• assertArraysEqual(...): asserts whether two arrays are equal.
• map(...): return a new array based on the results of the callback function.
• countOnly(...): return an object containing counts of everything that the input object listed.
