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 @michaeljgryzz/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actual, expected): asserts if two arrays are equal or not and logs the result
• assertEqual(actual, expected): asserts if two values are equal or not and logs the result
• assertObjectsEqual(actual, expected): asserts two objects and prints to the console whether or not they have matching contents
• countLetters(sentence): calculates the frequency of each letter in a sentence, excluding spaces
• countOnly(allItems, itemsToCount): counts occurrences of specified items in an array of strings, based on a criteria object
• eqArrays(array1, array2): takes in two arrays and returns true or false based on a perfect match
• eqObjects(object1, object2): takes in two objects and returns true if both objects have identical keys with identical values
• findKey(object, callback): searches for a key in an object that satisfies a provided callback function
• findKeyByValue(object, value): searches for a key in an object by the provided value
• flatten(array): converts an array with nested arrays into a single-level array
• head(array): returns the first element of an array
• letterPositions(sentence): returns the indices of each character in a string, excluding spaces
• middle(array): returns the middle element(s) of an array, or an empty array if there are fewer than 3 elements
• tail(array): returns a new array containing all elements of the input array except the first one
• takeUntil(array, callback): returns a slice of an array with elements taken from the beginning until the callback function returns truthy
• without(sourceArray, itemsToRemoveArray): returns a subset of an array by removing specified elements
