@idrking/lotide v1.0.1

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 @idrking/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(actualArray, expectedArray): Function that logs a string to the console based on the results of comparing two arrays (supports nested arrays)
• assertEqual(actual, expected): Function that logs a string to the console based on the results of comparing two non-array / non-object values
• assertObjectsEqual(actualObject, expectedObject): Function that logs a string to the console based on the results of comparing two objects (supports nested objects)
• countLetters(string): Function that returns an object with a count of each non-space character in a string
• countOnly(array, valuesToOmit): Function that returns an object with a count of each value in an array except any value specified in the valuesToOmit array
• eqArrays(arrayOne, arrayTwo): Function that compares two arrays and returns true if they match, false otherwise. Supports nested arrays
• eqObjects(objectOne, objectTwo): Function that compares two objects and returns true if they match, false otherwise. Supports nested objects
• findKey(object, callback): Function that takes in an object and a callback, executes the callback on each value in the array and then returns the corresponding key for the first value to return true
• findKeyByValue(object, value)" Function that takes in an object and any other value, and returns the first key that corresponds to that value
• flatten(array): Function that takes in an array and flattens it, taking nested arrays and adding their values in place to the return array.
• head(array): Function that returns the first element in an array
• letterPositions(string): Function that takes a string and returns an object with all the indices that each non-space character can be found at, as an object
• map(array, callback): Function that takes in an array and a callback function and returns an array populated with the results of calling the callback on each element of the array
• middle(array): Function that takes in an array and returns the middle element (if odd length) or middle two (if even) elements of an array
• tail(array): Function that returns an array with all elements of the original array except the first
• takeUntil(array, callback): Function that takes in an array and a callback, and executes the callback on each item, returning all values up until the first value on which the callback returns true
• without(array, itemsToRemove): Function that takes in two arrays, and returns a copy of the first array after removed all instances of any element found in the itemsToRemove array
