@paahn/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 @paahn/lotide

Require it:

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

Call it:

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

Documentation

The following functions are currently implemented:

• assertArraysEqual(array1, array2): determines if two arrays are identical
• assertEqual(actual, expected): determines if two items are identical
• assertObjectsEqual(actual, expected): determines if two objects are identical
• countLetters(inputString): counts how many occurences of the same letter in a string
• countOnly(allItems,itemsToCount): counts how many occurences of a name in an object
• eqArrays(array1, array2): checks if two arrays are identical
• eqObjects(obj1, obj2): takes in two objects and returns true or false, based on a perfect match
• findKey(obj, callback): takes an object and a callback function, calls the function to report the first occurence of a key.
• findKeyByValue(obj, value): takes in an object and a value,scans the object and returns the first key which contains the given value.
• flatten(array): takes in an array, if the array has other arrays in it, it removes the nested arrays
• head(array): returns the first element (aka head) of an array
• letterPositions(sentence): takes in a sentence and returns all the indices where each letter is found in the sentence
• map(item, callback): takes an item and a callback function and runs the callback on the item
• middle(array): returns an array containing the middle element of the input array
• tail(array): returns the array without the first element of the input array
• takeUntil(array, callback): keep collecting from the input array until the callback provided returns a truthy value.
• without(inputArr, itemsToRemove): Return a new array with only those elements from source that are not present in the removeFromArray.
