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 @diavolosz/lotide

Require it:

const _ = require('@diavolosz/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 the same
• assertEqual(actual, expected): asserts if two values are the same
• assertObjectsEqual(actual, expected): asserts if two objects are the same
• countLetters(stringInput): takes in a string, and outputs an object containing the count of each letter that appeared
• countOnly(allItems, itemsToCount): takes in an array and an object, returns anew object that contains the count of all elements present in that array if satisfy condition listed in object
• eqArrays(array1, array2): checks to see if two arrays are the same
• eqObjects(object1, object2): checks to see if two objects are the same
• findKey(objectList, callback): takes in object, and callback condition. if object contains callback condition, return the key
• findKeyByValue(object, value): takes in an object and a key, loops through object and return the key
• flatten(input): takes in an array of nested arrays, return new array containing all elements without any nested arrays
• head(array): takes in an array, returns first value in the array
• letterPositions(sentence): takes in a string, returns object with the letter positions (index)
• map(array, callback): takes in an array and callback function, returns array after modification by callback function
• middle(array): takes in an array, counts array length to determine even or odd, and then returns middle value if odd and two middle values if even
• tail(array): takes in an array, returns the rest after the first item
• takeUntil(array, callback): takes in an array and a callback function, return array items until callback function's requirements are satisfied
• without(selectedArray, itemsToRemove): takes in 2 arrays, returns a new array without the items listed in itemsToRemove
