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 @lucaspin/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• head() = Function used to retrieve the first element from the array
• tail() = Function used to retrieve every element except the head (first element) of the array.
• middle() = Function used to retrieve the middle elements of an array.
• assertArraysEqual() = Function for asserting that two arrays are equal.
• assertEqual() = Function used to help us test our code, comparing primitive types.
• assertObjectsEqual() = Function used to compare two objects.
• countLetters() = Function that takes in a string and return counts for the specific letter in the string.
• countOnly() = Function that takes in a collection of items and return counts for a specific subset of those items.
• eqArrays() = Function that can compare two arrays for a perfect match.
• eqObjects() = Function used to compare two objects.
• findKey() = Function that 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.
• findKeyByValue() = Function that help us search for a key on an object where its value matches a given value.
• flatten() = Function that when given an array with other arrays inside, it can flatten it into a single-level array.
• letterPositions() = Function which will return all the indices (zero-based positions) in the string where each character is found.
• map = Function that returns a new array based on the results of the callback function.
• takeUntil() = Function that returns a "slice of the array with elements taken from the beginning." It should keep going until the callback/predicate returns a truthy value.
• without() = Function used filter our data by removing some unwanted items.
